For a +C complete write-up, see the document "AUTOGRAPH - THE UNABRIDGED +C WRITE-UP". +C +C +C PACKAGE AUTOGRAPH +C +C LATEST REVISION January, 1986 +C +C PURPOSE To draw graphs, each with a labelled background +C and each displaying one or more curves. +C +C ACCESS (ON THE CRAY) To use AUTOGRAPH routines on the Cray, simply +C call them; they are in the binary library +C $NCARLB, which is automatically searched. +C +C To get smoother curves, drawn using spline +C interpolation, compile DASHSMTH, from ULIB, +C to replace DASHCHAR, from $NCARLB: +C +C GETSRC,LIB=ULIB,FILE=DASHSMTH,L=DSMTH. +C CFT,I=DSMTH,L=0. +C +C AUTOGRAPH contains a routine AGPWRT, which it +C calls to draw labels. This routine just passes +C its arguments on to the system-plot-package +C routine PWRIT. To use one of the fancier +C character-drawers, like PWRITX or PWRITY, +C just compile a routine AGPWRT to replace the +C default version; it has the same arguments as +C PWRIT and may either draw the character string +C itself, or just pass the arguments on to a +C desired character-drawer. The AUTOGRAPH +C specialist has some "standard" versions of +C AGPWRT and should be consulted for help in +C avoiding pitfalls. One standard version, +C which calls PWRITX, may be obtained using the +C following JCL: +C +C GETSRC,LIB=XLIB,FILE=AGUPWRITX,L=UPWRTX. +C CFT,I=UPWRTX,L=0. +C +C USAGE Following this indented preamble are given two +C lists: one describing the AUTOGRAPH routines +C and another describing the arguments of those +C routines. +C +C "AUTOGRAPH - THE UNABRIDGED WRITE-UP" gives +C a complete write-up of AUTOGRAPH, in great +C detail and with a set of helpful examples. +C +C ENTRY POINTS Except for seven routines which are included +C in the package for historical reasons (EZY, +C EZXY, EZMY, EZMXY, IDIOT, ANOTAT, and DISPLA), +C the AUTOGRAPH routines have six-character names +C beginning with the characters 'AG'. An alpha- +C betized list follows: +C +C AGAXIS AGBACK AGBNCH AGCHAX AGCHCU AGCHIL +C AGCHNL AGCTCS AGCTKO AGCURV AGDASH AGDFLT +C AGDLCH AGDSHN AGEXAX AGEXUS AGEZSU AGFPBN +C AGFTOL AGGETC AGGETF AGGETI AGGETP AGGTCH +C AGINIT AGKURV AGLBLS AGMAXI AGMINI AGNUMB +C AGPPID AGPWRT AGQURV AGRPCH AGRSTR AGSAVE +C AGSCAN AGSETC AGSETF AGSETI AGSETP AGSRCH +C AGSTCH AGSTUP AGUTOL +C +C NOTE: The "routine" AGDFLT is a block-data +C routine specifying the default values of +C AUTOGRAPH control parameters. +C +C SPECIAL CONDITIONS Under certain conditions, AUTOGRAPH may print +C an error message (via the routine SETER) and +C stop. Each error message includes the name of +C the routine which issued it. A description of +C the condition which caused the error may be +C found in the AUTOGRAPH write-up in the NCAR +C graphics manual; look in the write-up of the +C routine which issued the error message, under +C the heading 'SPECIAL CONDITIONS'. +C +C For error messages issued by the routine +C AGNUMB, see the write-up of the routine AGSTUP. +C +C If you get an error in the routine ALOG10, it +C probably means that you are using a logarithmic +C axis and some of the coordinate data along that +C axis are zero or negative. +C +C COMMON BLOCKS The AUTOGRAPH common blocks are AGCONP, AGORIP, +C AGOCHP, AGCHR1, and AGCHR2. AGCONP contains +C the AUTOGRAPH "control parameters", primary and +C secondary, all of which are real, AGORIP other +C real and/or integer parameters, AGOCHP other +C character parameters, AGCHR1 and AGCHR2 the +C variables implementing the character-storage- +C and-retrieval scheme of AUTOGRAPH. +C +C I/O Lower-level plotting routines are called to +C produce graphical output and, when errors +C occur, error messages may be written to the +C system error file, as defined by I1MACH(4), +C either directly or by way of a call to SETER. +C +C REQUIRED ULIB AUTOGRAPH uses the software dashed-line package +C ROUTINES DASHCHAR. Of course, either of the packages +C DASHSMTH or DASHSUPR may be used instead, to +C get smoother curves. +C +C SPECIALIST Dave Kennison, Scientific Computing Division, +C National Center for Atmospheric Research +C +C LANGUAGE FORTRAN +C +C HISTORY Dave Robertson wrote the original routine +C IDIOT, which was intended to provide a simple, +C quick-and-dirty, x-y graph-drawing capability. +C In time, as it became obvious that many users +C were adapting IDIOT to more sophisticated +C tasks, Dan Anderson wrote the first AUTOGRAPH +C package, based on IDIOT. It allowed the user +C to put more than one curve on a graph, to use +C more sophisticated backgrounds, to specify +C coordinate data in a variety of ways, and to +C more easily control the scaling and positioning +C of graphs. Eventually, this package, too, was +C found wanting. In 1977, Dave Kennison entirely +C re-wrote AUTOGRAPH, with the following goals: +C to maintain the ease of use for simple graphs +C which had been the principal virtue of the +C package, to provide the user with as much +C control as possible, to incorporate desirable +C new features, and to make the package as +C portable as possible. In 1984, the package +C was again worked over by Dave Kennison, to +C make it compatible with FORTRAN-77 and +C to remove any dependency on the LOC function, +C which had proved to cause difficulties on +C certain machines. The user interface was +C changed somewhat and some new features were +C added. A GKS-compatible version was written. +C +C SPACE REQUIRED AUTOGRAPH is big; one pays a price for its +C capabilities. On the Cray, it occupies a +C little under 30000 (octal) locations. The +C required plot package routines take about +C another 7000 (octal), the (modified) PORT +C support routines about another 1000 (octal), +C and system routines (math, I/O, miscellany) +C another 30000 (octal). +C +C PORTABILITY AUTOGRAPH may be ported with few modifications +C to most systems having a FORTRAN-77 compiler. +C +C The labelled common blocks may have to be +C declared in a part of the user program which +C is always core-resident so that variables +C in them will maintain their values from one +C AUTOGRAPH-routine call to the next. Such a +C problem may arise when AUTOGRAPH is placed in +C an overlay or when some sort of memory-paging +C scheme is used. +C +C REQUIRED RESIDENT AUTOGRAPH uses the DASHCHAR routines DASHDB, +C ROUTINES DASHDC, FRSTD, LASTD, LINED, AND VECTD, the +C system-plot-package routines FRAME, GETSET, +C GETSI, LINE, PWRIT, and SET, the support +C routines ISHIFT and IOR, the (modified) +C PORT utilities SETER and I1MACH, and the +C FORTRAN-library routines ALOG10, ATAN2, COS, +C SIN, AND SQRT. +C +C --------------------------------------------------------------------- +C U S E R - C A L L A B L E A U T O G R A P H R O U T I N E S +C --------------------------------------------------------------------- +C +C Following is a list of AUTOGRAPH routines to be called by the user +C (organized by function). Each routine is described briefly. The +C arguments of the routines are described in the next section. +C +C Each of the following routines draws a complete graph with one call. +C Each is implemented by a set of calls to the lower-level AUTOGRAPH +C routines AGSTUP, AGCURV, and AGBACK (which see, below). +C +C -- EZY (YDRA,NPTS,GLAB) - draws a graph of the curve defined by the +C data points ((I,YDRA(I)),I=1,NPTS), with a graph label specified +C by GLAB. +C +C -- EZXY (XDRA,YDRA,NPTS,GLAB) - draws a graph of the curve defined by +C the data points ((XDRA(I),YDRA(I)),I=1,NPTS), with a graph label +C specified by GLAB. +C +C -- EZMY (YDRA,IDXY,MANY,NPTS,GLAB) - draws a graph of the family of +C curves defined by data points (((I,YDRA(I,J)),I=1,NPTS),J=1,MANY), +C with a graph label specified by GLAB. The order of the subscripts +C of YDRA may be reversed - see the routine DISPLA, argument LROW. +C +C -- EZMXY (XDRA,YDRA,IDXY,MANY,NPTS,GLAB) - draws a graph of the +C family of curves defined by the data points (((XDRA(I),YDRA(I,J)), +C I=1,NPTS),J=1,MANY), with a graph label specified by GLAB. XDRA +C may be doubly-subscripted and the order of the subscripts of XDRA +C and YDRA may be reversed - see the routine DISPLA, argument LROW. +C +C -- IDIOT (XDRA,YDRA,NPTS,LTYP,LDSH,LABX,LABY,LABG,LFRA) - implements +C the routine from which AUTOGRAPH grew - not recommended - provided +C for antique lovers. +C +C The following routines provide user access to the AUTOGRAPH control +C parameters (in the labelled common block AGCONP). +C +C -- ANOTAT (XLAB,YLAB,LBAC,LSET,NDSH,DSHL) - may be used to change the +C x- and y-axis (non-numeric) labels, the background type, the way +C in which graphs are positioned and scaled, and the type of dash +C patterns to be used in drawing curves. +C +C -- DISPLA (LFRA,LROW,LTYP) - may be used to specify when, if ever, +C the EZ... routines do a frame advance, how input arrays for EZMY +C and EZMXY are dimensioned, and the linear/log nature of graphs. +C +C -- AGSETP (TPGN,FURA,LURA) - a general-purpose parameter-setting +C routine, used to set the group of parameters specified by TPGN, +C using values obtained from the array (FURA(I),I=1,LURA). +C +C -- AGSETF (TPGN,FUSR) - used to set the single parameter specified by +C TPGN, giving it the floating-point value FUSR. +C +C -- AGSETI (TPGN,IUSR) - used to set the single parameter specified by +C TPGN, giving it the floating-point value FLOAT(IUSR). +C +C -- AGSETC (TPGN,CUSR) - the character string CUSR is stashed in an +C array inside AUTOGRAPH and the floating-point equivalent of an +C identifier which may be used for later retrieval of the string is +C stored as the value of the single parameter specified by TPGN. The +C single parameter must be a label name, a dash pattern, the text of +C a label line, or the line-terminator character. +C +C -- AGGETP (TPGN,FURA,LURA) - a general-purpose parameter-getting +C routine, used to get the group of parameters specified by TPGN, +C putting the result in the array (FURA(I),I=1,LURA). +C +C -- AGGETF (TPGN,FUSR) - used to get, in FUSR, the floating-point +C value of the single parameter specified by TPGN. +C +C -- AGGETI (TPGN,IUSR) - used to get, in IUSR, the integer equivalent +C of the value of the single parameter specified by TPGN. +C +C -- AGGETC (TPGN,CUSR) - used to get, in CUSR, the character string +C whose identifier is specified by the integer equivalent of the +C single parameter specified by TPGN. The single parameter must +C be a label name, a dash pattern, the text of a label line, or the +C line-terminator character. +C +C The following are lower-level routines, which may be used to draw +C graphs of many different kinds. The EZ... routines call these. They +C are intended to be called by user programs, as well. +C +C -- AGSTUP (XDRA,NVIX,IIVX,NEVX,IIEX,YDRA,NVIY,IIVY,NEVY,IIEY) - this +C routine must be called prior to the first call to either of the +C two routines AGBACK and AGCURV, to force the set-up of secondary +C parameters controlling the behavior of those routines. After any +C parameter-setting call, AGSTUP must be called again before calling +C either AGBACK or AGCURV again. AGSTUP calls the routine "SET", in +C the plot package, so that user x/y coordinates in subsequent calls +C will map properly into the plotter space. +C +C -- AGBACK - draws the background defined by the current state of the +C AUTOGRAPH control parameters. +C +C -- AGCURV (XVEC,IIEX,YVEC,IIEY,NEXY,KDSH) - draws the curve defined +C by the arguments, positioning it as specified by the current state +C of the AUTOGRAPH control parameters. +C +C The following utility routines are called by the user. +C +C -- AGSAVE (IFNO) - used to save the current state of AUTOGRAPH by +C writing the appropriate information to a specified file. Most +C commonly used to save the default state for later restoration. +C This routine should be used instead of AGGETP when the object +C is to save the whole state of AUTOGRAPH, since it saves not only +C the primary control parameters, but all of the character strings +C pointed to by the primary control parameters. It is the user's +C responsibility to position the file before calling AGSAVE. +C +C -- AGRSTR (IFNO) - used to restore a saved state of AUTOGRAPH by +C reading the appropriate information from a specified file. Most +C commonly used to restore AUTOGRAPH to its default state. It is +C the user's responsibility to position the file before calling +C AGRSTR. +C +C -- AGBNCH (IDSH) - a function, of type CHARACTER*16 (it must be +C declared as such in a user routine referencing it), whose value, +C given a 16-bit binary dash pattern, is the equivalent character +C dash pattern. +C +C -- AGDSHN (IDSH) - a function, of type CHARACTER*16 (it must be +C declared as such in a user routine referencing it), whose value, +C given an integer "n" (typically between 1 and 26) is the character +C string 'DASH/ARRAY/nnnn.', which is the name of the nth dash +C pattern parameter. To set the 13th dash pattern, for example, +C one might use "CALL AGSETC (AGDSHN(13),'$$$$$$CURVE 13$$$$$$')". +C +C The following utility routines are called by AUTOGRAPH. The versions +C included in AUTOGRAPH itself are dummies; they do nothing but RETURN. +C The user may replace one or more of these routines with versions to +C accomplish specific purposes. +C +C -- AGUTOL (IAXS,FUNS,IDMA,VINP,VOTP) - called by AUTOGRAPH to perform +C the mapping from user-system values along an axis to label-system +C values along the axis and vice-versa. This routine may be replaced +C by the user to create a desired graph. +C +C -- AGCHAX (IFLG,IAXS,IPRT,VILS) - called by AUTOGRAPH just before and +C just after the various parts of the axes are drawn. +C +C -- AGCHCU (IFLG,KDSH) - called by AUTOGRAPH just before and just after +C each curve is drawn. +C +C -- AGCHIL (IFLG,LBNM,LNNO) - called by AUTOGRAPH just before and just +C after each line of an informational label is drawn. +C +C -- AGCHNL (IAXS,VILS,CHRM,MCIM,NCIM,IPXM,CHRE,MCIE,NCIE) - called by +C AUTOGRAPH just after the character strings defining a numeric label +C have been generated. +C +C --------------------------------------------------------------------- +C D E S C R I P T I O N S O F A R G U M E N T S +C --------------------------------------------------------------------- +C +C In calls to the routines EZY, EZXY, EZMY, and EZMXY: +C +C -- XDRA is an array of x coordinates, dimensioned as implied by the +C current value of the AUTOGRAPH control parameter 'ROW.' (see the +C description of the argument LROW, below). The value of the +C AUTOGRAPH parameter 'NULL/1.' (1.E36, by default) when used as an +C x coordinate, implies a missing data point; the curve segments +C on either side of such a point are not drawn. +C +C -- YDRA is an array of y coordinates, dimensioned as implied by the +C current value of the AUTOGRAPH control parameter 'ROW.' (see the +C description of the argument LROW, below). The value of the +C AUTOGRAPH parameter 'NULL/1.' (1.E36, by default) when used as a +C y coordinate, implies a missing data point; the curve segments +C on either side of such a point are not drawn. +C +C -- IDXY is the first dimension of the arrays XDRA (if it has two +C dimensions) and YDRA. +C +C -- MANY is the number of curves to be drawn by the call to EZ... - +C normally, the second dimension of XDRA (if it has two dimensions) +C and YDRA. +C +C -- NPTS is the number of points defining each curve to be drawn by +C the routine EZ... - normally, the first (or only) dimension of +C XDRA and YDRA. +C +C -- GLAB is a character constant or a character variable, defining a +C label to be placed at the top of the graph. The string may not be +C more than 40 characters long - if it is fewer than 40 characters +C long, its last character must be a dollar sign. (The dollar sign +C is not a part of the label - it is stripped off.) The character +C string "CHAR(0)" may be used to indicate that the previous label, +C whatever it was, should continue to be used. The initial graph +C label consists of blanks. +C +C In calls to the routine ANOTAT: +C +C -- XLAB and YLAB resemble GLAB (see above) and define labels for the +C x and y axes. The default x-axis label is the single character +C X, the default y-axis label the single character Y. Note that one +C may use the string "CHAR(0)" to indicate that the x-axis (y-axis) +C label is not to be changed from what it was previously. +C +C -- LBAC, if non-zero, specifies a new value for the AUTOGRAPH control +C parameter 'BACKGROUND.', as follows: +C +C 1 - a perimeter background +C +C 2 - a grid background +C +C 3 - an axis background +C +C 4 - no background +C +C The default value of 'BACKGROUND.' is 1. +C +C -- LSET, if non-zero, specifies a new value for the AUTOGRAPH control +C parameter 'SET.'. This parameter may be negated to suspend the +C drawing of curves by the EZ... routines, so that a call to one of +C them will produce only a background. The absolute value of 'SET.' +C affects the way in which AUTOGRAPH determines the position and +C shape of the graph and the scaling of the axes, as follows: +C +C 1 - Restores the default values of the AUTOGRAPH parameters +C in question. AUTOGRAPH will set up an appropriate call +C to the plot-package routine "SET", over-riding any prior +C call to that routine. +C +C 2 - Tells AUTOGRAPH to use arguments 1-4 and 9 of the last +C "SET" call. Arguments 1-4 specify where the graph should +C fall on the plotter frame, argument 9 whether the graph +C is linear/linear, linear/log, etc. +C +C 3 - Tells AUTOGRAPH to use arguments 5-8 and 9 of the last +C "SET" call. Arguments 5-8 specify the scaling of the +C axes, argument 9 whether the graph is linear/linear, +C linear/log, etc. +C +C 4 - A combination of 2 and 3. Arguments 1-4 of the last "SET" +C call specify the position, arguments 5-8 the scaling, and +C argument 9 the linear/log nature, of the graph. +C +C (The plot-package routine "SET" is described in the NCAR Graphics +C Manual; it is not a part of AUTOGRAPH.) +C +C If the routine DISPLA is called with its argument LTYP non-zero, +C the linear/log nature of the graph will be that specified by LTYP, +C not that specified by the last "SET" call, no matter what the value +C of the control parameter 'SET.'. +C +C The default value of 'SET.' is 1. +C +C -- NDSH, if non-zero, specifies a new value of the AUTOGRAPH control +C parameter 'DASH/SELECTOR.' (and therefore a new set of dashed-line +C patterns), as described below. Note: The default value of the +C dashed-line parameters is such that all curves will be drawn using +C solid lines; if that is what you want, use a zero for NDSH. +C +C If the value of 'DASH/SELECTOR.' is negative, curves produced +C by subsequent calls to EZMY or EZMXY will be drawn using a +C set of alphabetic dashed-line patterns. The first curve drawn +C by a given call will be labelled 'A', the second 'B', ..., the +C twenty-sixth 'Z', the twenty-seventh 'A' again, and so on. +C Curves drawn by calls to EZY and EZXY will be unaffected. +C +C If the value of 'DASH/SELECTOR.' is positive, it must be less +C than or equal to 26. The next argument, DSHL, is an array +C containing NDSH dashed-line patterns. All curves produced by +C subsequent calls to EZY, EZXY, EZMY, and EZMXY will be drawn +C using the dashed-line patterns in (DSHL(I),I=1,NDSH) - the +C first curve produced by a given call will have the pattern +C specified by DSHL(1), the second that specified by DSHL(2), +C the third that specified by DSHL(3), . . . the NDSH+1st that +C specified by DSHL(1), . . . etc. Each element of DSHL must +C be a character string, in which a dollar sign stands for a +C solid-line segment, a quote stands for a gap, and other +C characters stand for themselves. See the write-up of the +C package "DASHCHAR". Binary dashed-line patterns may not be +C defined by means of a call to ANOTAT, only by means of calls +C to lower-level routines. +C +C -- DSHL (if NDSH is greater than zero) is an array of dashed-line +C patterns, as described above. +C +C In calls to the routine DISPLA: +C +C -- LFRA, if non-zero, specifies a new value for the AUTOGRAPH control +C parameter 'FRAME.'. Possible values are as follows: +C +C 1 - The EZ... routines do a frame advance after drawing. +C +C 2 - No frame advance is done by the EZ... routines. +C +C 3 - The EZ... routines do a frame advance before drawing. +C +C The default value of 'FRAME.' is 1. +C +C -- LROW, if non-zero, specifies a new value for the AUTOGRAPH control +C parameter 'ROW.'. This parameter tells AUTOGRAPH how the argument +C arrays XDRA and YDRA, in calls to the routines EZMY and EZMXY, are +C subscripted, as follows: +C +C If 'ROW.' is positive, this implies that the first subscript +C of YDRA is a point number and the second subscript is a curve +C number. If 'ROW.' is negative, the order is reversed. +C +C If the absolute value of 'ROW.' is 1, this implies that XDRA +C is singly-subscripted, by point number only. If the absolute +C value of 'ROW.' is 2 or greater, this implies that XDRA is +C doubly-subscripted, just like YDRA. +C +C The default value of 'ROW.' is 1, spicifying that XDRA is singly- +C subscripted and that YDRA is doubly-subscripted by point number +C and curve number, in that order. +C +C -- LTYP, if non-zero, specifies new values for the AUTOGRAPH control +C parameters 'X/LOGARITHMIC.' and 'Y/LOGARITHMIC.', which determine +C whether the X and Y axes are linear or logarithmic. Possible +C values are as follows: +C +C 1 - x axis linear, y axis linear +C +C 2 - x axis linear, y axis logarithmic +C +C 3 - x axis logarithmic, y axis linear +C +C 4 - x axis logarithmic, y axis logarithmic +C +C The default values of these parameters make both axes linear. +C +C If the parameters 'X/LOGARITHMIC.' and 'Y/LOGARITHMIC.' are reset +C by the routine DISPLA, they are given values which make them +C immune to being reset when 'SET.' = 2, 3, or 4 (see the discussion +C of the argument LSET, above). +C +C In calls to the routines AGSETP, AGSETF, AGSETI AGSETC, AGGETP, +C AGGETF, AGGETI, and AGGETC: +C +C -- TPGN is a character string identifying a group of AUTOGRAPH +C control parameters. It is of the form 'K1/K2/K3/ . . . /Kn.'. +C Each Ki is a keyword. The keyword K1 specifies a group of control +C parameters, K2 a subgroup of that group, K3 a subgroup of that +C subgroup, etc. See the AUTOGRAPH write-up in the graphics manual +C for a more complete description of these parameter-group names and +C the ways in which they may be abbreviated. +C +C -- FURA is an array, from which control-parameter values are to be +C taken (the routine AGSETP) or into which they are to be stored +C (the routine AGGETP). Note that the array is real; all of the +C AUTOGRAPH parameters are stored internally as reals. +C +C -- LURA is the length of the user array FURA. +C +C -- FUSR is a variable, from which a single control parameter value is +C to be taken (the routine AGSETF) or in which it is to be returned +C (the routine AGGETF). Note that the variable is real. +C +C -- IUSR is a variable, from which a single-control parameter value is +C to be taken (the routine AGSETI) or in which it is to be returned +C (the routine AGGETI). Note that, since the control parameters are +C stored internally as reals, each of the routines AGSETI and AGGETI +C does a conversion - from integer to real or vice-versa. Note also +C that AGSETI and AGGETI should only be used for parameters which +C have intrinsically integral values. +C +C -- CUSR is a character variable from which a character string is to +C be taken (the routine AGSETC) or into which it is to be retrieved +C (the routine AGGETC). The control parameter affected by the call +C contains the floating-point equivalent of an integer identifier +C returned by the routine which stashes the character string and +C tendered to the routine which retrieves it (sort of the automated +C equivalent of a hat check). Note that AGSETC and AGGETC should +C only be used for parameters which intrinsically represent character +C strings. +C +C In calls to the routine AGSTUP: +C +C -- XDRA is an array of x coordinates of user data - usually, but not +C necessarily, the same data which will later be used in calls to +C the routine AGCURV. +C +C -- NVIX is the number of vectors of data in XDRA - if XDRA is doubly- +C dimensioned, NVIX would normally have the value of its second +C dimension, if XDRA is singly-dimensioned, a 1. +C +C -- IIVX is the index increment between vectors in XDRA - if XDRA is +C doubly-dimensioned, IIVX would normally have the value of its +C first dimension, if XDRA is singly-dimensioned, a dummy value. +C +C -- NEVX is the number of elements in each data vector in XDRA - if +C XDRA is doubly-dimensioned, NEVX would normally have the value of +C its first dimension, if XDRA is singly-dimensioned, the value of +C that single dimension. +C +C -- IIEX is the index increment between elements of a data vector in +C XDRA - normally a 1. +C +C -- YDRA, NVIY, IIVY, NEVY, and IIEY are analogous to XDRA, NVIX, +C IIVX, NEVX, and IIEX, but define y-coordinate data. +C +C In calls to the routine AGCURV: +C +C -- XVEC is a vector of x coordinate data. +C +C -- IIEX is the index increment between elements in XVEC. AGCURV will +C use XVEC(1), XVEC(1+IIEX), XVEC(1+2*IIEX), etc. +C +C -- YVEC is a vector of y coordinate data. +C +C -- IIEY is the index increment between elements in YVEC. AGCURV will +C use YVEC(1), YVEC(1+IIEY), YVEC(1+2*IIEY), etc. +C +C -- NEXY is the number of points defining the curve to be drawn. +C +C -- KDSH is a dashed-line selector. Possible values are as follows: +C +C If KDSH is zero, AUTOGRAPH will assume that the user has +C called the routine DASHD (in the DASHCHAR package, which see) +C to define the dashed-line pattern to be used. +C +C If KDSH is less than zero and has absolute value M, AUTOGRAPH +C will use the Mth (modulo 26) alphabetic dashed-line pattern. +C Each of these patterns defines a solid line interrupted every +C so often by a letter of the alphabet. +C +C If KDSH is greater than zero and has the value M, AUTOGRAPH +C will use the Mth (modulo N) dashed-line pattern in the group +C of N dashed-line patterns defined by the AUTOGRAPH control +C parameters in the group named 'DASH/PATTERNS.'. The default +C values of these parameters specify solid lines. +C +C In calls to the routines AGSAVE and AGRSTR: +C +C -- IFNO is the unit number associated with a file to which a single +C unformatted logical record of data is to be written, or from which +C such a record is to be read, by AUTOGRAPH. The file is not rewound +C before being written or read; positioning it properly is the user's +C responsibility. +C +C In calls to the function AGBNCH: +C +C -- IDSH is a 16-bit binary dash pattern, the character equivalent of +C which is to be returned as the value of AGBNCH. +C +C In calls to the function AGDSHN: +C +C -- IDSH is the number of the dash pattern parameter whose name is to +C be returned as the value of the function AGDSHN. +C +C In calls to the routine AGUTOL: +C +C -- IAXS is the number of the axis. The values 1, 2, 3, and 4 imply +C the left, right, bottom, and top axes, respectively. +C +C -- FUNS is the value of the parameter 'AXIS/s/FUNCTION.' which may be +C used to select the desired mapping function for axis IAXS. It is +C recommended that the default value (zero) be used to specify the +C identity mapping. A non-zero value may be integral (1., 2., etc.) +C and serve purely to select the code to be executed or it may be the +C value of a real parameter in the equations defining the mapping. +C +C -- IDMA specifies the direction of the mapping. A value greater than +C zero indicates that VINP is a value in the user system and that +C VOTP is to be a value in the label system, a value less than zero +C the opposite. +C +C -- VINP is an input value in one coordinate system along the axis. +C +C -- VOTP is an output value in the other coordinate system along the +C axis. +C +C In calls to the routine AGCHAX: +C +C -- IFLG is zero if a particular object is about to be drawn, non-zero +C if it has just been drawn. +C +C -- IAXS is the number of the axis being drawn. The values 1, 2, 3, +C and 4 indicate the left, right, bottom, and top axes, respectively. +C +C -- IPRT indicates the part of the axis being drawn. Possible values +C are as follows: +C +C -- 1 implies the line of the axis. +C +C -- 2 implies a major tick. +C +C -- 3 implies a minor tick. +C +C -- 4 implies the mantissa of a numeric label. +C +C -- 5 implies the exponent of a numeric label. +C +C -- VILS is the value in the label system at the point where the part +C is being drawn. For IPRT = 1, VILS is zero. +C +C In calls to the routine AGCHCU: +C +C -- IFLG is zero if a particular object is about to be drawn, non-zero +C if it has just been drawn. +C +C -- KDSH is the value with which AGCURV was called, as follows: +C +C AGCURV called by Value of KDSH +C ---------------- ---------------------------------------- +C EZY 1 +C EZXY 1 +C EZMY "n" or "-n", where n is the curve number +C EZMXY "n" or "-n", where n is the curve number +C the user program the user value +C +C In calls to the routine AGCHIL: +C +C -- IFLG is zero if a particular object is about to be drawn, non-zero +C if it has just been drawn. +C +C -- LBNM is a character variable containing the name of the label being +C drawn. +C +C -- LNNO is the number of the line being drawn. +C +C In calls to the routine AGCHNL: +C +C -- IAXS is the number of the axis being drawn. The values 1, 2, 3, +C and 4 imply the left, right, bottom, and top axes, respectively. +C +C -- VILS is the value to be represented by the numeric label, in the +C label system for the axis. The value of VILS must not be altered. +C +C -- CHRM, on entry, is a character string containing the mantissa of +C the numeric label, as it will appear if AGCHNL makes no changes. +C If the numeric label includes a "times" symbol, it is represented +C by a blank in CHRM. (See IPXM, below.) CHRM may be modified. +C +C -- MCIM is the length of CHRM - the maximum number of characters that +C it will hold. The value of MCIM must not be altered. +C +C -- NCIM, on entry, is the number of meaningful characters in CHRM. If +C CHRM is changed, NCIM should be changed accordingly. +C +C -- IPXM, on entry, is zero if there is no "times" symbol in CHRM; if +C it is non-zero, it is the index of a character position in CHRM. +C If AGCHNL changes the position of the "times" symbol in CHRM, +C removes it, or adds it, the value of IPXM must be changed. +C +C -- CHRE, on entry, is a character string containing the exponent of +C the numeric label, as it will appear if AGCHNL makes no changes. +C CHRE may be modified. +C +C -- MCIE is the length of CHRE - the maximum number of characters that +C it will hold. The value of MCIE must not be altered. +C +C -- NCIE, on entry, is the number of meaningful characters in CHRE. If +C CHRE is changed, NCIE should be changed accordingly. +C +C --------------------------------------------------------------------- +C T H E A U T O G R A P H C O D E +C --------------------------------------------------------------------- +C +C Following is the AUTOGRAPH code. Routines appear in alphabetic order. +C + SUBROUTINE AGAXIS (IAXS,QTST,QSPA,WCWP,HCWP,XBGA,YBGA,XNDA,YNDA, + + QLUA,UBGA,UNDA,FUNS,QBTP,BASE,QJDP,WMJL,WMJR, + + QMNT,QNDP,WMNL,WMNR,QLTP,QLEX,QLFL,QLOF,QLOS, + + DNLA,WCLM,WCLE,RFNL,QCIM,QCIE,WNLL,WNLR,WNLB, + + WNLE) +C +C The routine AGAXIS is used to draw, tick-mark, and label an axis or, +C if ITST is non-zero, to pre-compute the amount of space which will be +C required for numeric labels when the axis is actually drawn. AGAXIS +C assumes that the last call to the plot-package routine SET was as +C follows (or the equivalent thereof): +C +C CALL SET (XLCW,XRCW,YBCW,YTCW,0.,1.,0.,1.,1) +C +C where XLCW, XRCW, YBCW, and YTCW are the coordinates of the left, +C right, bottom, and top edges of the curve window, stated as fractions +C of the appropriate edge of the plotter frame. +C +C The arguments of AGAXIS are as follows: +C +C -- IAXS is the number of the axis being drawn - 1, 2, 3, or 4, meaning +C the left, right, bottom, and top axes, respectively. +C +C -- ITST is an integer specifying what the caller wishes AGAXIS to do, +C as follows: +C +C -- If ITST .LT. 0, AGAXIS is to draw only the axis, nothing else. +C +C -- If ITST .EQ. 0, AGAXIS is to draw, tick, and label the axis. +C +C -- If ITST .GT. 0, AGAXIS is to pre-compute the amount of space +C which will be required for numeric labels. If the labels will +C not fit in the space provided, AGAXIS is instructed to take +C action as follows: +C +C -- ITST .EQ. 1 - no action. +C +C -- ITST .EQ. 2 - shrink the labels. +C +C -- ITST .EQ. 3 - re-orient the labels. +C +C -- ITST .EQ. 4 - shrink and/or re-orient the labels. +C +C -- ISPA is a 0 or a 1, specifying whether or not the axis itself is +C to be drawn. If ISPA .NE. 0, the axis is suppressed. Tick marks +C and/or labels may still be drawn. +C +C -- WCWP is the width of the curve window, in plotter units. +C +C -- HCWP is the height of the curve window, in plotter units. +C +C -- XBGA, YBGA, XNDA, and YNDA are the x and y coordinates of the ends +C of the axis. X coordinates are stated as fractions of the width, +C y coordinates as fractions of the height, of the curve window. The +C axis to be drawn must be either horizontal or vertical (at an angle +C of 0, 90, 180, or 270 degrees). The left side, right side, begin- +C ning, and end of the axis are defined from the viewpoint of a demon +C standing at (XBGA,YBGA) and staring balefully toward (XNDA,YNDA). +C +C -- LLUA, UBGA, and UNDA define the mapping of the "user" coordinate +C system (used for data-point coordinates) onto the axis. If LLUA +C is zero, the mapping is linear; if LLUA is non-zero, the mapping +C is logarithmic. UBGA is the user-system value at the beginning of +C the axis, UNDA the value at the end of the axis. The subroutine +C AGFTOL, which needs these parameters, is actually passed LLUA, +C UBEG=F(UBGA), and UDIF=F(UNDA)-F(UBGA), where F is the function +C F(X)=X or the function F(X)=ALOG10(X), depending on LLUA. +C +C -- FUNS is a function-selector, to be used in calls to AGUTOL, which +C defines the mappings from the user system to the label system and +C vice-versa for each of the four axes. The functions defined must +C be continuous, monotonic, and bounded within the user-system range +C (UBGA,UNDA) and a little bit outside that range. The positions +C of numeric labels and tick marks are chosen in the label system, +C mapped to the user system, and then onto the axis. +C +C -- NBTP and BASE specify how major ticks are to be positioned in the +C label coordinate system. See the routine AGNUMB (arguments NBTP, +C SBSE, and EXMU) for a description of these arguments. Note that +C NBTP .EQ. 0 or BASE .EQ. 0. suppresses both major tick marks and +C their labels. Note: SBSE .EQ. +BASE or -BASE, as needed. +C +C -- QJDP is the major-tick-mark dash pattern (0. .LE. QJDP .LE. 65535.) +C QJDP .LE. 0 suppresses major ticks. +C +C -- WMJL and WMJR are the distances to the left and right ends of the +C major tick marks, stated as fractions of the shortest side of the +C curve window. Values .EQ. 0 may be used to suppress one or both +C portions. Values .GE. 1 may be used to extend a given portion all +C the way to the edge of the curve window. (See routine AGCTKO.) +C +C -- NMNT is the number of minor tick marks to be placed between each +C pair of consecutive major tick marks. NMNT .EQ. 0 suppresses them. +C +C -- QNDP, WMNL, and WMNR are analogous to QJDP, WMJL, and WMJR, but +C specify minor-tick-mark characteristics. +C +C -- NLTP, NLEX, and NLFL specify the graphic form of numeric labels, as +C described in the routine AGNUMB (which see). Note that NLTP .LE. 0 +C suppresses numeric labels. +C +C -- NLOF and NLOS are first and second choices for the numeric label +C orientation. Both must be multiples of 90, specifying an angle +C measured in degrees counter-clockwise from a vector running from +C left to right in the curve window. If ITST .EQ. 0, AGAXIS uses +C NLOF if it is .GE. 0, NLOS otherwise, for the label orientation. +C If ITST .NE. 0, AGAXIS initially makes both NLOF and NLOS positive. +C Then, if ITST .GE. 3, NLOF may or may not be made negative. (To +C set the sign of NLOF or NLOS, AGAXIS adds or subtracts 360*K.) +C +C -- DNLA is the desired distance of numeric labels from the axis, +C positive to the left, negative to the right, of the axis. The +C magnitude of DNLA is the size of the gap between the axis and the +C nearest edge of a label, expressed as a fraction of the smaller +C dimension of the curve window. See also RFNL, below. +C +C -- WCLM and WCLE are the desired widths of characters in the mantissa +C or the exponent, respectively, of numeric labels, expressed as a +C fraction of the smaller dimension of the curve window. See also +C RFNL, below. +C +C -- RFNL is a reduction factor, used as a multiplier for DNLA, WCLM, +C and WCLE. If ITST .NE. 0, RFNL is initially set to 1. - then, if +C ITST .EQ. 2 or 4, it is reset as necessary to shrink the labels. +C +C -- MCIM and MCIE specify the maximum number of characters in the +C mantissa and exponent, respectively, of a numeric label. These +C are input parameters if ITST .EQ. 0, output parameters otherwise. +C +C -- WNLL, WNLR, WNLB, and WNLE are the widths of numeric-label strips +C on the left side, on the right side, at the beginning, and at the +C end, of the axis. These are both input and output parameters of +C AGAXIS. On input, they specify the amount of space available for +C numeric labels - on output, they specify the amount of space used +C (if ITST .EQ. 0) or required (if ITST .NE. 0). Each is stated as +C a fraction of either the width or the height of the curve window, +C depending on the orientation of the axis in the curve window. +C +C The following common block contains other AUTOGRAPH variables, both +C real and integer, which are not control parameters. The only ones +C actually used here are ISLD, MWCM, MWCE, and MDLA. ISLD is a solid- +C line dash pattern (sixteen one bits). MWCM, MWCE, and MDLA specify +C the minimum allowed values of the width of a character in a label +C mantissa, the width of a character in a label exponent, and the +C distance of a label from the axis. All are in plotter coordinate +C units. +C + COMMON /AGORIP/ SMRL , ISLD , MWCL,MWCM,MWCE,MDLA,MWCD,MWDQ , + + INIF +C +C The AUTOGRAPH function AGFPBN is of type integer. +C + INTEGER AGFPBN +C +C Local data required are as follows: +C +C BFRM is a buffer in which the routine AGNUMB returns the characters of +C a label mantissa.

Each label is assumed to lie in one of +C five boxes, as follows: +C +C Box 1 is to the left of the curve window. +C Box 2 is to the right of the curve window. +C Box 3 is below the curve window. +C Box 4 is above the curve window. +C Box 5 is the curve window itself. +C Box 6 is the entire plot (graph) window. +C +C A test run of AGLBLS returns two sets of box dimensions to the caller. +C DBOX contains the dimensions required if all labels are to have their +C desired sizes, SBOX the dimensions required if all labels are to have +C their smallest sizes. The caller is expected to use this information +C to determine a final set of box dimensions (stored in DBOX), and then +C call AGLBLS again to actually draw the labels in those boxes. +C +C The arguments of AGLBLS are as follows: +C +C -- ITST specifies whether the call is a test call (ITST .LE. 0) or a +C real call (ITST .GT. 0). If ABSV(ITST) .GT. 1, AGLBLS is allowed +C to shrink the labels if they would not otherwise fit in their box. +C If ABSV(ITST) .EQ. 1, shrinkage of labels is prohibited. If ITST +C .EQ. 0, labels are suppressed. +C +C -- WCWP and HCWP are the width and height of the curve window, in +C plotter-coordinate-system units. AGLBLS assumes that the last call +C to the plot package routine "SET" had arguments XLCW, XRCW, YBCW, +C YTCW, 0., 1., 0., 1., and 1 - defining the most convenient system +C of coordinates for it. +C +C -- FLLB is the array in which the label list is stored. The array is +C doubly-dimensioned. The first subscript specifies one of ten label +C attributes, the second a particular label. The attributes are as +C follows (the name ILLB(M,N) refers to a label attribute which is +C intrinsically an integer, despite being stored as a real): +C +C -- ILLB(1,N) specifies the name of label N. If ILLB(1,N) is zero, +C no label is defined. Otherwise, ILLB(1,N) is an identifier +C returned by AGSTCH when the name of the label (a character +C string) was stored away. +C +C -- ILLB(2,N) may be set non-zero to suppress label N. +C +C -- FLLB(3,N) and FLLB(4,N) are the x and y coordinates of a base- +C point relative to which label N is positioned, as fractions of +C the width and height, respectively, of the curve window. The +C position of the base-point determines the box in which label N +C is considered to lie. +C +C -- FLLB(5,N) and FLLB(6,N) are small offsets (typically about the +C size of a character width), stated as fractions of the smaller +C side of the curve window. They are used to offset the label +C base-point (after the box number is determined). Typically, +C this provides a minimum spacing between the label and one side +C of the curve window. +C +C -- ILLB(7,N) is the orientation angle of the label, in degrees +C counter-clockwise from horizontal. The base-line for label N +C is a vector emanating from the base-point at this angle. The +C specified angle must be a multiple of 90 degrees. +C +C -- ILLB(8,N) is the centering option for the label. It specifies +C how each line of the label is to be positioned relative to a +C line perpendicular to the base-line at the base-point. +C +C -- If ILLB(8,N) .LT. 0, the left edge of each line lies on +C the perpendicular. +C +C -- If ILLB(8,N) .EQ. 0, the center of each line lies on the +C perpendicular. +C +C -- If ILLB(8,N) .GT. 0, the right edge of each line lies on +C the perpendicular. +C +C -- ILLB(9,N) is the number of lines in label N. +C +C -- ILLB(10,N) is the second subscript (in the line list) of the +C first line of label N. +C +C -- LBIM is the maximum number of labels the label list will hold. +C +C -- FLLN is the array in which the line list is stored. The array is +C doubly-dimensioned. The first subscript specifies one of six line +C attributes, the second a particular line. The attributes are as +C follows (the name ILLN(M,N) refers to a line attribute which is +C intrinsically an integer, despite being stored as a real): +C +C -- ILLN(1,N) is the position number of line N. The lines of a +C label are ordered according to their position numbers, the one +C having the largest position number being top-most. Moreover, +C lines having position numbers .GT. 0 are placed above the label +C base-line, those having position numbers .EQ. 0 (of which there +C should be but one) are placed on the label base-line, and those +C having position numbers .LT. 0 are placed below the label base- +C line. The magnitudes of the position numbers have nothing to +C do with inter-line spacing - that is up to AGLBLS to determine. +C +C -- ILLN(2,N) may be set non-zero to suppress line N. +C +C -- FLLN(3,N) is the desired width of characters in the line, as a +C fraction of the smaller side of the curve window. +C +C -- ILLN(4,N) is the identifier of the character string comprising +C the text of the line, as returned by AGSTCH at the time the +C string was stored. +C +C -- ILLN(5,N) is the number of characters in the line. +C +C -- ILLN(6,N) is the index of the next line of the label. The +C lines of a label must be ordered by position number (largest +C to smallest). +C +C -- DBOX and SBOX, dimensioned 6 X 4, contain box dimensions, as dis- +C cussed above. D/SBOX(M,N) is the Nth edge-coordinate of box M, +C where N .EQ. 1 for the left edge, 2 for the right edge, 3 for the +C bottom edge, and 4 for the top edge, of the box. The first two are +C stated as fractions of the width, the second two as fractions of +C the height, of the curve window. +C +C RBOX, dimensioned 6, holds reduction factors for the sizes of the +C characters in labels in each of the six boxes. Each RBOX(M) is +C +C -- negative to specify smallest-size characters, or +C +C -- zero to specify that no reduction factor has been chosen, or +C +C -- positive, between 0. and 1.

The arguments of AGNUMB are as follows: +C +C -- NBTP is an integer specifying the type of number to be converted. +C There are three possibilities: +C +C NBTP = 1 - number of the form SBSE * EXMU. +C +C NBTP = 2 - number of the form SBSE * 10**EXMU. +C +C NBTP = 3 - number of the form SIGN(SBSE) * ABSV(SBSE)**EXMU. +C +C -- SBSE is a base value for a set of labels. See NBTP description. +C +C -- EXMU is an exponent or a multiplier for a given label. Although it +C is a floating-point number, its value should be integral, unless +C NBTP equals 1 and/or NLTP equals 1. Using a non-integral EXMU in +C other cases will have undesirable effects. See NBTP description. +C +C -- NLTP is an integer specifying the type of label to be generated. +C There are three possibilities: +C +C -- NLTP = 1 - label is to have an exponent portion and is to be +C expressed in scientific notation. +C +C -- NLTP = 2 - label is to have an exponent portion and is to be +C expressed in a form determined by the number type NBTP. +C +C -- NLTP = 3 - label is to have no exponent portion and is to be +C expressed in a form determined by the number type NBTP. +C +C The possible label types will be described in greater detail below. +C +C -- NLEX (when used) is an integer specifying (in a manner depending on +C the values of other parameters) the value of the exponent portion +C of the label. See the detailed discussion of label types, below. +C +C -- NLFL (when used) is an integer specifying (in a manner depending on +C the values of other parameters) the length of the fractional por- +C tion of the mantissa of the label. See the detailed discussion of +C label types, below. +C +C -- BFRM is a character variable in which the mantissa portion of the +C label is to be returned. +C +C -- MCIM specifies the maximum number of characters BFRM can hold. +C +C -- NCIM is the number of characters returned in BFRM by AGNUMB. +C +C -- IPXM is the position of the character X in the mantissa. If IPXM +C is zero, the character X does not occur in the mantissa. +C +C -- BFRE, MCIE, and NCIE are analogous to BFRM, MCIM, and NCIM, but +C pertain to the exponent portion of the label. +C +C Label types: AGNUMB will produce many different types of labels, as +C directed by the various input parameters. Each of these is described +C below. The general form of a label is +C +C (-) (1/) (I) (.) (F) (X 10) (E) +C +C where the parentheses are used to mark portions which may either be +C present or absent. The minus sign is included only if the label value +C is negative. I is the integer portion of the mantissa, included only +C if its value is non-zero. The decimal point is included if the input +C parameter NLFL does not specifically direct that it should be omitted +C or if the fractional portion of the mantissa (F) is present. F is the +C fractional portion of the mantissa. The "X 10" is included if it is +C appropriate, and is considered to be a part of the mantissa; if it is +C included, a blank is actually returned for the character X, so the +C routine which plots the label should construct this character by +C drawing two short lines. E is the exponent, returned in a separate +C buffer so that it may be plotted in a superscript form. The possible +C label types are, then, as follows: +C +C -- Scientific notation - if the label type NLTP equals 1, the form +C +C (-) (I) (.) (F) X 10 (E) +C +C is used. NLEX specifies the length of I (thus also specifying the +C value of the exponent E). If NLEX is .LE. 0, I is omitted. If +C NLEX is .LT. 0 and has the absolute value N, the fraction F is +C forced to have N leading zeroes. NLFL specifies the length of F. +C If NLFL is .LE. 0, F is omitted. If NLFL is .LT. 0, the decimal +C point is omitted. If (I.F) has the value 1, (I.F X) is omitted. +C If the entire label has zero value, the character 0 is used. +C +C -- Exponential, but non-scientific notation - if the label type NLTP +C equals 2, the form used depends on the argument NBTP, as follows: +C +C -- If NBTP equals 1 (number of the form SBSE * EXMU), the form +C +C (-) (I) (.) (F) X 10 (E) +C +C is used. NLEX specifies the value of the exponent E. The +C length of F is specified by NLFL. If NLFL is .LE. 0, F is +C omitted. If NLFL is .LT. 0, the decimal point is omitted. If +C the label value is exactly 0, the character 0 is used. +C +C -- If NBTP equals 2 (number of the form SBSE*10**EXMU), the form +C +C (-) (I) (.) (F) X 10 (E) +C +C is used. The exponent E has the value NLEX+EXMU. The length +C of F is specified by NLFL. If NLFL is .LE. 0, F is omitted. +C If NLFL is .LT. 0, the decimal point is omitted. If the label +C value is exactly 0, the character 0 is used. If (I.F) has the +C value 1., then (I.F X) is omitted. +C +C -- If NBTP equals 3, specifying that the number is of the form +C SIGN(SBSE) * ABSV(SBSE)**EXMU, the form +C +C (-) (I) (.) (F) (E) +C +C is used. The exponent E has the value EXMU. The length of F +C is specified by NLFL. If NLFL is .LE. 0, F is omitted. If +C NLFL is .LT. 0, the decimal point is omitted. +C +C -- No-exponent notation - if the label type NLTP equals 3, the form +C used depends on the argument NBTP, as follows: +C +C -- If NBTP equals 1 (number of the form SBSE * EXMU), the form +C +C (-) (I) (.) (F) +C +C is used. NLFL specifies the length of F. If NLFL is .LE. 0, +C F is omitted. If NLFL is .LT. 0, the decimal point is omitted. +C If the entire label has zero value, the character 0 is used. +C +C -- If NBTP equals 2 (number of the form SBSE*10**EXMU), the form +C +C (-) (I) (.) (F) +C +C is used. The length of F is specified by the function +C +C MAX(NLFL,0)-EXMU (if EXMU is .LT. MAX(NLFL,0)) +C MIN(NLFL,0) (if EXMU is .GE. MAX(NLFL,0)) +C +C which may appear somewhat formidable, but produces a simple, +C desirable result. Suppose, for example, that SBSE = 3.6, +C NLFL = 1, and EXMU ranges from -3 to +3 - the labels produced +C are as follows: +C +C .0036 .036 .36 3.6 36. 360. 3600. +C +C NLFL may be viewed as specifying the length of F if EXMU is 0. +C If the value of the function is .LE. 0, F is omitted - if its +C value is .LT. 0, the decimal point is omitted. +C +C -- If NBTP equals 3, specifying that the number is of the form +C SIGN(SBSE) * ABSV(SBSE)**EXMU, the form +C +C (-) (I) (.) (F) +C +C is used if EXMU is positive (or zero), and the form +C +C (-) 1 / (I) (.) (F) +C +C is used if EXMU is negative. The length of F is specified by +C the function +C +C NLFL * ABSV(EXMU) (if EXMU is .NE. 0) +C MIN(NLFL,0) (if EXMU is .EQ. 0) +C +C Again, this function produces a simple result. Suppose that +C SBSE = 1.1, NLFL = 1, and EXMU ranges from -3 to +3 - the +C labels produced are as follows: +C +C 1/1.331 1/1.21 1/1.1 1. 1.1 1.21 1.331 +C +C NLFL may be viewed as specifying the length of F if EXMU is 1. +C If the value of the function is .LE. 0, F is omitted - if its +C value is .LT. 0, the decimal point is omitted. As another +C example, suppose that SBSE = 2., NLFL = -1, and EXMU ranges +C from -4 to +4.

THE GRID IS SCANNED ONCE FOR +C EACH CONTOUR LEVEL AND ALL CONTOURS AT THAT +C LEVEL ARE PLOTTED. +C THERE ARE TWO METHODS OF INTERPOLATION. THE +C FIRST IS A SMOOTH DATA INTERPOLATION +C SCHEME BASED ON LAWSON'S C1 +C SURFACE INTERPOLATION ALGORITHM, WHICH HAS +C BEEN REFINED BY HIROSHA AKIMA. PARTS OF +C AKIMA'S ALGORITHM ARE USED IN THIS PACKAGE. +C SEE THE "REFERENCE" SECTION BELOW. +C THE SECOND IS A LINEAR INTERPOLATION SCHEME. +C WHEN DATA IS SPARSE IT IS USUALLY BETTER TO +C USE THE C1 INTERPOLATION. IF YOU HAVE DENSE +C DATA (OVER 100 POINTS) THEN THE LINEAR +C INTERPOLATION WILL GIVE THE BETTER RESULTS. +C +C PORTABILITY ANSI FORTRAN +C +C +C OPERATION CALL CONRAN (XD,YD,ZD,NDP,WK,IWK,SCRARR) +C +C FRAME MUST BE CALLED BY THE USER. +C +C CONRAN HAS MANY OPTIONS, EACH OF WHICH MAY +C BE CHANGED BY CALLING ONE OF THE FOUR +C SUBROUTINES CONOP1, CONOP2, CONOP3, OR +C CONOP4. THE NUMBER OF ARGUMENTS TO EACH +C CONOP ROUTINE IS THE SAME AS THE FINAL +C SUFFIX CHARACTER IN THE ROUTINE'S NAME. +C +C THE CONOP ROUTINES ARE CALLED BEFORE CONRAN +C IS CALLED, AND VALUES SET BY THESE CALLS +C CONTINUE TO BE IN EFFECT UNTIL THEY ARE +C CHANGED BY ANOTHER CALL TO A CONOP ROUTINE. +C +C ALL THE CONOP ROUTINES HAVE AS THEIR FIRST +C ARGUMENT A CHARACTER STRING TO IDENTIFY THE +C OPTION BEING CHANGED. THIS IS THE ONLY +C ARGUMENT TO CONOP1. CONOP2 HAS AN INTEGER +C SECOND ARGUMENT. CONOP3 HAS A REAL ARRAY (OR +C CONSTANT) AS ITS SECOND ARGUMENT AND AN +C INTEGER (USUALLY THE DIMENSION OF THE +C ARRAY) AS ITS THIRD ARGUMENT. CONOP4 HAS A +C CHARACTER STRING AS ITS SECOND ARGUMENT AND +C INTEGERS FOR THE THIRD AND FOURTH ARGUMENTS. +C +C ONLY THE FIRST TWO CHARACTERS ON EACH SIDE OF +C THE EQUAL SIGN ARE SCANNED. THEREFORE ONLY 2 +C CHARACTERS FOR EACH OPTION ARE REQUIRED ON +C INPUT TO CONOP (I.E. 'SCA=PRI' AND 'SC=PR' +C ARE EQUIVALENT.) +C +C REMEMBER, THERE MUST BE AT LEAST 4 DATA POINTS. +C THIS IS EQUAL TO THE DEFAULT NUMBER OF +C DATA POINTS TO BE USED FOR ESTIMATION OF PAR- +C TIAL DERIVATIVES AT EACH DATA POINT. +C THE ESTIMATED PARTIAL DERIVATIVES ARE +C USED FOR THE CONSTRUCTION OF THE INTERPOLAT- +C ING POLYNOMIAL'S COEFFICIENTS. +C +C LISTED BELOW ARE OPTIONS WHICH CAN ENHANCE +C YOUR PLOT. AN EXAMPLE OF AN APPROPRIATE +C CONOP CALL IS GIVEN FOR EACH OPTION. A +C COMPLETE LIST OF DEFAULT SETTINGS FOLLOWS +C THE LAST OPTION. +C +C OPTIONS +C +C CHL THIS FLAG DETERMINES HOW THE HIGH AND LOW +C CONTOUR VALUES ARE SET. THESE CONTOUR VALUES +C MAY BE SET BY THE PROGRAM OR BY THE USER. IF +C CHL=OFF, THE PROGRAM EXAMINES THE USER'S IN- +C PUT DATA AND DETERMINES BOTH THE HIGH AND LOW +C VALUES. IF CHL=ON, THE USER MUST SPECIFY THE +C DESIRED HIGH (HI) AND LOW (FLO) VALUES. +C THE DEFAULT IS CHL=OFF. +C +C IF PROGRAM SET: CALL CONOP3('CHL=OFF',0.,0) +C +C IF USER SET: CALL CONOP3('CHL=ON',ARRAY,2) +C WHERE ARRAY(1)=HI, ARRAY(2)=FLO +C +C NOTE: THE VALUES SUPPLIED FOR CONTOUR INCRE- +C MENT AND CONTOUR HIGH AND LOW VALUES ASSUMES +C THE UNSCALED DATA VALUES.

THE INCREMENT IS EITHER +C CALCULATED BY THE PROGRAM (CIL=OFF) USING THE +C RANGE OF HIGH AND LOW VALUES FROM THE USER'S +C INPUT DATA, OR SET BY THE USER (CIL=ON). THE +C DEFAULT IS CIL=OFF. +C +C IF PROGRAM SET: CALL CONOP3('CIL=OFF',0.,0) +C +C IF USER SET: CALL CONOP3('CIL=ON',CINC,1) +C +C NOTE: BY DEFAULT, THE PROGRAM WILL EXAMINE +C THE USER'S INPUT DATA AND DETERMINE THE CONTOUR +C INTERVAL (CINC) AT SOME APPROPRIATE RANGE BETWEEN +C THE LEVEL OF HIGH AND LOW VALUES SUPPLIED, USUALLY +C GENERATING BETWEEN 15 AND 20 CONTOUR LEVELS. +C ELS. +C +C EXAMPLE: CALL CONOP3('CIL=ON',15.,1) +C WHERE 15.

THE DEFAULT IS OFF. +C +C IF PROGRAM SET: CALL CONOP3('CON=OFF',0.,0) +C +C IF USER SET: CALL CONOP3('CON=ON',ARRAY,NCL) +C +C NOTE: THE ARRAY (ARRAY) CONTAINS THE CONTOUR +C LEVELS (FLOATING POINT ONLY) AND NCL IS THE +C NUMBER OF LEVELS. THE MAXIMUM NUMBER OF CON- +C TOUR LEVELS ALLOWED IS 30. WHEN ASSIGNING +C THE ARRAY OF CONTOUR VALUES, THE VALUES MUST +C BE ORDERED FROM SMALLEST TO LARGEST. +C +C EXAMPLE: +C DATA RLIST(1),...,RLIST(5)/1.,2.,3.,10.,12./ +C +C CALL CONOP3('CON=ON',RLIST,5) WHERE +C 'RLIST' CONTAINS THE USER SPECIFIED +C CONTOUR LEVELS, AND 5 IS THE +C NUMBER OF USER SPECIFIED CONTOUR +C LEVELS (NCL). +C +C WARNING ON CONTOUR OPTIONS: +C IT IS ILLEGAL TO USE THE CON OPTION WHEN +C EITHER CIL OR CHL ARE ACTIVATED. IF +C THIS IS DONE, THE OPTION CALL THAT DETECTED +C THE ERROR WILL NOT BE EXECUTED. +C +C DAS THIS FLAG DETERMINES WHICH CONTOURS ARE +C REPRESENTED BY DASHED LINES. THE USER SETS +C THE DASHED LINE PATTERN. THE USER MAY SPECI- +C FY THAT DASHED LINES BE USED FOR CONTOURS +C WHOSE VALUE IS LESS THAN, EQUAL TO, OR +C GREATER THAN THE DASH PATTERN BREAKPOINT (SEE +C THE DBP OPTION BELOW), WHICH IS ZERO BY +C DEFAULT.

RECALL THAT IN +C FORTRAN 77, IN A QUOTED STRING A SINGLE QUOTE +C IS REPRESENTED BY TWO SINGLE QUOTES (''). +C +C EXAMPLE: +C CALL CONOP4('DAS=GTR','$$$$$''$$$$',0,0) +C +C DBP THIS FLAG DETERMINES HOW THE DASH PATTERN +C BREAK POINT (BP) IS SET. IF DBP=ON, BP MUST +C BE SET BY THE USER BY SPECIFYING BP. IF +C DBP=OFF THE PROGRAM WILL SET BP TO THE +C DEFAULT VALUE WHICH IS ZERO. +C +C IF PROGRAM SET: CALL CONOP3('DBP=OFF',0.,0) +C +C IF USER SET: CALL CONOP3('DBP=ON',BP,1) +C +C NOTE: BP IS A FLOATING POINT NUMBER WHERE THE +C BREAK FOR GTR AND LSS CONTOUR DASH PATTERNS +C ARE DEFINED.

IF SSZ=ON, THE +C USER SETS ISTEP, OR, IF SSZ=OFF, THE PROGRAM +C WILL AUTOMATICALLY SET ISTEP AT THE DEFAULT +C VALUE OF 40. +C +C IF PROGRAM SET: CALL CONOP2('SSZ=OFF',0) +C +C IF USER SET: CALL CONOP2('SSZ=ON',ISTEP) +C +C NOTE: ISTEP IS AN INTEGER SPECIFYING THE DENSITY +C OF THE VIRTUAL GRID. IN MOST CASES, THE DEFAULT +C VALUE OF 40 PRODUCES PLEASING CONTOURS. FOR +C COARSER BUT QUICKER CONTOURS, LOWER THE +C VALUE. FOR SMOOTHER CONTOURS AT +C THE EXPENSE OF TAKING LONGER TIME, RAISE +C THE VALUE. NOTE: FOR STEP SIZES GREATER +C THAN 200 IN CONRAN, THE ARRAYS PV IN COMMON +C CONRA1 AND ITLOC IN COMMON CONRA9, MUST BE +C EXPANDED TO ABOUT 10 MORE THAN ISTEP. +C SEE CONRA1 AND CONRA9 COMMENTS BELOW FOR MORE +C INFORMATION. +C +C EXAMPLE: CALL CONOP2('SSZ=ON',25) +C THIS ISTEP VALUE WILL PRO- +C DUCE A COARSE CONTOUR. +C +C STL FLAG TO DETERMINE THE SIZE OF THE TITLE. +C ISZSTL MAY BE SET BY THE USER (STL=ON), OR +C THE PROGRAM WILL SET IT TO THE DEFAULT SIZE +C OF 16 PLOTTER ADDRESS UNITS (STL=OFF). +C +C IF PROGRAM SET: CALL CONOP2('STL=OFF',0) +C +C IF USER SET: CALL CONOP2('STL=ON',ISZSTL) +C +C NOTE: WHEN 30 OR 40 CHARACTERS ARE USED FOR +C THE TITLE, THE DEFAULT SIZE OF 16 PLOTTER +C ADDRESS UNITS WORKS WELL. FOR LONGER TITLES, +C A SMALLER TITLE SIZE IS REQUIRED. +C +C EXAMPLE: CALL CONOP2('STL=ON',13) +C +C TEN FLAG TO DETERMINE THE TENSION FACTOR APPLIED +C WHEN SMOOTHING CONTOUR LINES. THE USER MAY +C SET TENS OR ALLOW THE PROGRAM TO SET THE +C VALUE. IF USER SET, TENS MUST HAVE A VALUE +C GREATER THAN ZERO AND LESS THAN OR EQUAL TO +C 30. THE DEFAULT VALUE IS 2.5. +C +C IF PROGRAM SET: CALL CONOP3('TEN=OFF',0.,0) +C +C IF USER SET: CALL CONOP3('TEN=ON',TENS,1) +C +C NOTE: TENS IS NOT AVAILABLE IN THE STANDARD +C VERSION OF CONRAN. +C SMOOTHING OF CONTOUR LINES IS ACCOMPLISHED +C WITH SPLINES UNDER TENSION. TO ADJUST THE +C AMOUNT OF SMOOTHING APPLIED, ADJUST THE TEN- +C SION FACTOR. SETTING TENS VERY LARGE +C (I.E. 30.), EFFECTIVELY SHUTS OFF SMOOTHING. +C +C EXAMPLE: CALL CONOP3('TEN=ON',14.,1) +C +C TFR FLAG TO ADVANCE THE FRAME BEFORE TRIANGULATION. +C THE DEFAULT VALUE IS TFR=ON, WHICH MEANS THAT +C THE CONTOURS AND THE TRIANGLES WILL BE PLOTTED +C ON SEPARATE FRAMES. +C +C IF PROGRAM SET: CALL CONOP1('TFR=ON') +C +C TO TURN OFF: CALL CONOP1('TFR=OFF') +C +C NOTE: TRIANGLES ARE PLOTTED AFTER THE CON- +C TOURING IS COMPLETED. TO SEE THE TRIANGLES +C OVER THE CONTOURS, TURN THIS SWITCH OFF. +C +C TLE FLAG TO PLACE A TITLE AT THE TOP OF THE PLOT. +C IF TLE=ON, THE USER MUST SPECIFY CHARS AND +C INUM. CHARS IS THE CHARACTER STRING CONTAINING +C THE TITLE. INUM IS THE NUMBER OF CHARACTERS +C IN CHARS. THE DEFAULT VALUE IS OFF. +C +C TO TURN ON: CALL CONOP4('TLE=ON',CHARS,INUM,0) +C +C TO TURN OFF: CALL CONOP4('TLE=OFF',' ',0,0) +C +C NOTE: IF LONGER THAN 64-CHARACTER TITLES ARE +C DESIRED, THE CHARACTER VARIABLE ISTRNG FOUND +C IN CONRA7 MUST BE INCREASED APPROPRIATELY. +C +C EXAMPLE: CALL CONOP4('TLE=ON','VECTOR REVIEW' +C ,13,0) +C +C TOP FLAG TO PLOT ONLY THE TRIANGLES. +C +C TO TURN OFF: CALL CONOP1('TOP=OFF') +C +C TO TURN ON: CALL CONOP1('TOP=ON') +C +C NOTE: THE USER MAY WISH TO OVERLAY THE TRIAN- +C GLES ON SOME OTHER PLOT. 'TOP=ON' WILL +C ALLOW THAT. THIS OPTION WHEN ACTIVATED +C (TOP=ON), WILL SET TRI=ON, AND TFR=OFF. IF +C THE USER WANTS TFR=ON, IT SHOULD BE SET AFTER +C TOP IS SET. IF THE USER SETS TOP=OFF IT WILL +C SET TRI=OFF AND TFR=ON. IF THE USER WANTS TRI +C OR TFR DIFFERENT, SET THEM AFTER THE +C TOP CALL. +C +C TRI FLAG TO PLOT THE TRIANGULATION. THE DEFAULT IS +C OFF AND THEREFORE THE TRIANGLES ARE NOT DRAWN. +C +C TO TURN ON: CALL CONOP1('TRI=ON') +C +C TO TURN OFF: CALL CONOP1('TRI=OFF') +C +C NOTE: PLOTTING THE TRIANGLES WILL INDICATE TO +C THE USER WHERE GOOD AND BAD POINTS OF INTER- +C POLATION ARE OCCURRING IN THE CONTOUR MAP. +C EQUILATERAL TRIANGLES ARE OPTIMAL FOR INTER- +C POLATION.

THE +C ORIGIN AND ORIENTATION OF THE PROJECTION ARE +C SELECTED BY THE USER. POINTS ON THE EARTH +C DEFINED BY LATITUDE AND LONGITUDE ARE MAPPED +C TO POINTS IN THE PLANE OF PROJECTION - THE +C U/V PLANE. THE U AND V AXES ARE PARALLEL TO +C THE X AND Y AXES OF THE PLOTTER, RESPECTIVELY. +C A RECTANGULAR FRAME WHOSE SIDES ARE PARALLEL +C TO THE U AND V AXES IS CHOSEN AND MATERIAL +C WITHIN THAT FRAME (OR AN INSCRIBED ELLIPTICAL +C FRAME) IS PLOTTED. +C +C USAGE THE ROUTINE MAPDRW DRAWS A COMPLETE MAP, AS +C DIRECTED BY THE CURRENT VALUES OF PARAMETERS +C IN THE EZMAP PACKAGE. TO CHANGE THE VALUES +C OF THOSE PARAMETERS, AND THUS THE APPEARANCE +C OF THE MAP, ONE MAY FIRST CALL ONE OF THE +C ROUTINES MAPROJ (TO CHANGE THE PROJECTION TO +C BE USED), MAPSET (TO CHANGE WHAT PORTION OF +C THE U/V PLANE IS TO BE VIEWED), MAPPOS (TO +C CHANGE WHAT PORTION OF THE PLOTTER FRAME IS +C TO BE USED), OR ONE OF THE PARAMETER-SETTING +C ROUTINES MAPSTC, MAPSTI, MAPSTL, AND MAPSTR +C (TO CHANGE VARIOUS OTHER PARAMETERS, OF TYPES +C CHARACTER, INTEGER, LOGICAL, AND REAL). THE +C PARAMETER-RETRIEVAL ROUTINES MAPGTC, MAPGTI, +C MAPGTL, AND MAPGTR ALLOW THE USER TO RETRIEVE +C THE VALUES OF EZMAP PARAMETERS. +C +C THE ROUTINE MAPSAV ALLOWS ONE TO SAVE THE +C CURRENT STATE OF EZMAP, THE ROUTINE MAPRST TO +C RESTORE A SAVED STATE. +C +C USERS WITH SPECIAL NEEDS MAY WISH TO CALL THE +C LOWER-LEVEL ROUTINES MAPINT (TO INITIALIZE +C THE PACKAGE - IT MUST BE CALLED INITIALLY AND +C AGAIN WHENEVER CERTAIN PARAMETERS ARE CHANGED), +C MAPGRD (TO DRAW PARALLELS AND MERIDIANS), +C MAPLBL (TO LABEL THE INTERNATIONAL DATE LINE, +C THE EQUATOR, THE GREENWICH MERIDIAN, AND THE +C POLES, AND TO DRAW THE PERIMETER), AND MAPLOT +C (TO DRAW THE SELECTED GEOGRAPHIC OUTLINES). +C THESE ROUTINES ARE NORMALLY CALLED BY MAPDRW. +C +C INTENSITIES OF VARIOUS MAP PORTIONS MAY BE SET +C BY CALLS TO THE ROUTINE MAPSTI. THE ROUTINE +C MAPUSR IS CALLED BY EZMAP JUST BEFORE/AFTER +C DRAWING VARIOUS PORTIONS OF THE MAP; THE +C DEFAULT VERSION, WHICH DOES NOTHING, MAY BE +C REPLACED BY A USER VERSION WHICH SETS/RESTORES +C COLOR, SPOT SIZE, INTENSITY, DASH PATTERN, ETC. +C +C THE ROUTINE MAPEOS IS CALLED BY EZMAP ONCE FOR +C EACH OUTLINE SEGMENT. THE USER MAY SUPPLY A +C VERSION WHICH EXAMINES THE SEGMENT TO SEE IF +C IT OUGHT TO BE PLOTTED AND, IF NOT, TO DELETE +C IT. THIS MAY BE USED, FOR EXAMPLE, TO REDUCE +C THE CLUTTER IN NORTHERN CANADA. +C +C TO OVERLAY OBJECTS OF ONE'S OWN ON THE MAP +C DRAWN BY MAPDRW, ONE MAY USE ONE OR MORE OF +C THE ROUTINES MAPTRN (TO COMPUTE THE U/V +C COORDINATES OF A POINT, GIVEN ITS LATITUDE +C AND LONGITUDE), MAPIT (TO DO "PEN-UP/DOWN" +C MOVES), MAPFST (TO DO "PEN-UP" MOVES), AND +C MAPVEC (TO DO "PEN-DOWN" MOVES). +C +C THE ROUTINE SUPMAP, FROM WHICH EZMAP GREW, IS +C IMPLEMENTED WITHIN IT AND ALLOWS ONE TO DRAW +C A COMPLETE MAP WITH A SINGLE, RATHER LENGTHY, +C CALL. THE ROUTINE SUPCON, WHICH IS THE OLD +C ANALOGUE OF MAPTRN, IS ALSO IMPLEMENTED. +C +C THE OLD ROUTINE EZMAP, WHICH WAS IMPLEMENTED +C IN SUCH A WAY AS TO CAUSE PORTABILITY PROBLEMS, +C HAS BEEN REMOVED. STATISTICS INDICATED THAT +C IT WAS NOT BEING USED, ANYWAY. +C +C SEE THE WRITE-UPS OF INDIVIDUAL ROUTINES BELOW. +C +C I/O GRAPHICAL OUTPUT IS GENERATED.

L. PARKER OF UCSD WROTE THE +C ORIGINAL CODE CALLED SUPERMAP, USING OUTLINE +C DATA GENERATED BY HERSHEY. THIS WAS ADAPTED +C FOR USE AT NCAR BY LEE, IN 1968. REVISIONS +C OCCURRED IN JANUARY OF 1969 AND MAY OF 1971. +C THE CODE WAS PUT IN STANDARD NSSL FORMAT IN +C OCTOBER OF 1973. FURTHER REVISIONS OCCURRED +C IN JULY, 1974, IN AUGUST, 1976, AND IN JULY, +C 1978. IN LATE 1984 AND EARLY 1985, THE CODE +C WAS HEAVILY REVISED TO ACHIEVE FORTRAN-77 AND +C GKS COMPATIBILITY, TO REMOVE ERRORS, AND TO +C EXPAND THE OUTLINE DATASETS. CICELY RIDLEY, +C JAY CHALMERS, AND DAVE KENNISON (THE CURRENT +C CURATOR) HAVE ALL HAD A HAND IN THE CREATION +C OF THIS PACKAGE. +C +C REFERENCES HERSHEY, A.V., "THE PLOTTING OF MAPS ON A +C CRT PRINTER."

UNIVERSITY OF LONDON +C PRESS, 1962. +C +C ACCURACY THE DEFINITION OF THE MAP PRODUCED IS LIMITED +C BY TWO FACTORS: THE RESOLUTION OF THE OUTLINE +C DATA AND THE RESOLUTION OF THE GRAPHICS +C DEVICE. +C +C DATA POINTS IN THE CONTINENTAL OUTLINES ARE +C ABOUT ONE DEGREE APART AND THE COORDINATES +C ARE ACCURATE TO .01 DEGREE. DATA POINTS IN +C U.S. STATE OUTLINES ARE ABOUT .05 DEGREES +C APART AND THE COORDINATES ARE ACCURATE TO +C .001 DEGREE. BOTH THE SPACING AND THE +C ACCURACY OT THE INTERNATIONAL BOUNDARIES +C FALLS SOMEWHERE BETWEEN THESE TWO EXTREMES. +C +C THE DICOMED HAS 15-BIT COORDINATE REGISTERS, +C BUT AN EFFECTIVE RESOLUTION OF AT MOST 1 IN +C 4096 IN BOTH X AND Y. +C +C TIMING THE MARCH, 1985, UPDATE HAS MADE EZMAP RUN +C SIGNIFICANTLY SLOWER. THIS IS MOSTLY BECAUSE +C THE DEFAULT RESOLUTION HAS BEEN INCREASED TO +C A VALUE SUITABLE FOR THE DICOMED, RATHER THAN +C THE DD80. USERS WHO ARE CONCERNED ABOUT THIS +C MAY INCREASE THE VALUES OF THE PARAMETERS 'MV' +C AND/OR 'DD' (SEE THE DESCRIPTION OF MAPSTX) +C TO DECREASE THE TIMING (AT THE EXPENSE OF PLOT +C QUALITY, OF COURSE). +C +C PORTABILITY THE CODE IS WRITTEN IN FORTRAN-77 AND SHOULD +C BE VERY PORTABLE.

THREE DIMENSIONAL ARRAY OF DATA THAT DEFINES +C THE ISO-VALUED SURFACE. +C +C LU +C FIRST DIMENSION OF T IN THE CALLING PROGRAM. +C +C MU +C THE NUMBER OF DATA VALUES OF T TO BE +C PROCESSED IN THE U

T IS +C CONSIDERED TO BE IN A BOX WITH OPPOSITE +C CORNERS (1,1,1) AND (MU,MV,MW). THE EYE IS +C AT (EYE(1),EYE(2),EYE(3)), WHICH MUST BE +C OUTSIDE THE BOX THAT CONTAINS T. WHILE GAINING +C EXPERIENCE WITH THE ROUTINE, A GOOD CHOICE +C FOR EYE MIGHT BE (5.0*MU,3.5*MV,2.0*MW). +C +C MUVWP2 +C THE MAXIMUM OF (MU,MV,MW)+2; THAT IS, +C MUVWP2 = MAX(MU,MV,MW)+2). +C +C SLAB +C A WORK SPACE USED FOR INTERNAL STORAGE. SLAB +C MUST BE AT LEAST MUVWP2*MUVWP2 WORDS LONG. +C +C TISO +C THE ISO-VALUE USED TO DEFINE THE SURFACE. THE +C SURFACE DRAWN WILL SEPARATE VOLUMES OF T THAT +C HAVE VALUES GREATER THAN OR EQUAL TO TISO FROM +C VOLUMES OF T THAT HAVE VALUES LESS THAN TISO. +C +C IFLAG +C THIS FLAG SERVES TWO PURPOSES. +C . FIRST, THE ABSOLUTE VALUE OF IFLAG +C DETERMINES WHICH TYPES OF LINES ARE DRAWN +C TO APPROXIMATE THE SURFACE. THREE TYPES +C OF LINES ARE CONSIDERED: LINES OF +C CONSTANT U, LINES OF CONSTANT V AND LINES +C OF CONSTANT W. THE FOLLOWING TABLE LISTS +C THE TYPES OF LINES DRAWN. +C +C LINES OF CONSTANT +C ----------------- +C IABS(IFLAG) U V W +C ----------- --- --- --- +C 1 NO NO YES +C 2 NO YES NO +C 3 NO YES YES +C 4 YES NO NO +C 5 YES NO YES +C 6 YES YES NO +C 0, 7 OR MORE YES YES YES +C +C . SECOND, THE SIGN OF IFLAG DETERMINES WHAT +C IS INSIDE AND WHAT IS OUTSIDE, HENCE, +C WHICH LINES ARE VISIBLE AND WHAT IS DONE +C AT THE BOUNDARY OF T. FOR IFLAG: +C +C POSITIVE T VALUES GREATER THAN TISO ARE +C ASSUMED TO BE INSIDE THE SOLID +C FORMED BY THE DRAWN SURFACE. +C NEGATIVE T VALUES LESS THAN TISO ARE +C ASSUMED TO BE INSIDE THE SOLID +C FORMED BY THE DRAWN SURFACE. +C IF THE ALGORITHM DRAWS A CUBE, REVERSE THE +C SIGN OF IFLAG. +C +C ON OUTPUT T,LU,MU,LV,MV,MW,EYE,MUVWP2,TISO AND IFLAG ARE +C UNCHANGED. SLAB HAS BEEN WRITTEN IN. +C +C NOTE . THIS ROUTINE IS FOR LOWER RESOLUTION ARRAYS +C THAN ISOSRFHR. 40 BY 40 BY 40 IS A +C PRACTICAL MAXIMUM. +C . TRANSFORMATIONS CAN BE ACHIEVED BY +C ADJUSTING SCALING STATEMENT FUNCTIONS IN +C ISOSRF, SET3D AND TR32. +C . THE HIDDEN-LINE ALGORITHM IS NOT EXACT, SO +C VISIBILITY ERRORS CAN OCCUR. +C . THREE-DIMENSIONAL PERSPECTIVE CHARACTER +C LABELING OF ISOSRF IS POSSIBLE BY USING +C THE UTILITY PWRZI.

The +C default version does nothing. A user may supply his own version to +C change the numeric labels. For each numeric label, this routine is +C called twice by AGAXIS - once to determine how much space will be +C required when the label is actually drawn and once just before it +C is actually drawn. The arguments are as follows: +C +C - IAXS is the number of the axis being drawn. Its value is 1, 2, 3, +C or 4, implying the left, right, bottom, or top axes, respectively. +C The value of IAXS must not be altered. +C +C - VILS is the value to be represented by the numeric label, in the +C label system for the axis. The value of VILS must not be altered. +C +C - CHRM, on entry, is a character string containing the mantissa of the +C numeric label, as it will appear if AGCHNL makes no changes. If the +C numeric label includes a "times" symbol, it will be represented by +C a blank in CHRM. (See IPXM, below.) CHRM may be modified. +C +C - MCIM is the length of CHRM - the maximum number of characters that +C it will hold. The value of MCIM must not be altered. +C +C - NCIM, on entry, is the number of meaningful characters in CHRM. If +C CHRM is changed, NCIM should be changed accordingly. +C +C - IPXM, on entry, is zero if there is no "times" symbol in CHRM; if it +C is non-zero, it is the index of the appropriate character position +C in CHRM. If AGCHNL changes the position of the "times" symbol in +C CHRM, removes it, or adds it, the value of IPXM must be changed. +C +C - CHRE, on entry, is a character string containing the exponent of the +C numeric label, as it will appear if AGCHNL makes no changes. CHRE +C may be modified. +C +C - MCIE is the length of CHRE - the maximum number of characters that +C it will hold. The value of MCIE must not be altered. +C +C - NCIE, on entry, is the number of meaningful characters in CHRE.

SINCE UU AND VV ARE THE LONGITUDINAL AND LATITUDINAL COMPONENTS, +C RESPECTIVELY, OF A VELOCITY VECTOR HAVING UNITS OF DISTANCE OVER TIME, +C 1.E-6*UU/COS(LATITUDE) AND 1.E-6*VV REPRESENT THE CHANGE IN LONGITUDE +C AND LATITUDE, RESPECTIVELY, OF A PARTICLE MOVING WITH THE FLOW FIELD +C FOR A VERY SHORT PERIOD OF TIME. THE ROUTINE MAPTRN IS USED TO FIND +C THE POSITION OF THE PARTICLE'S PROJECTION AT THE BEGINNING AND END OF +C THAT TINY TIME SLICE AND, THEREFORE, THE DIRECTION IN WHICH TO DRAW +C THE ARROW REPRESENTING THE VELOCITY VECTOR SO THAT IT WILL BE TANGENT +C TO A PROJECTED FLOW LINE OF THE FIELD AT THAT POINT. THE VALUES U +C AND V ARE COMPUTED SO AS TO GIVE THE ARROW THE LENGTH IMPLIED BY UU +C AND VV. (THE CODE ENSURES THAT SQRT(U**2+V**2) IS EQUAL TO +C SQRT(UU**2+VV**2).) THE LENGTH OF THE ARROW REPRESENTS THE MAGNITUDE +C OF THE VELOCITY VECTOR, UNAFFECTED BY PERSPECTIVE. THE SCALING SET +C UP BY VELVCT WILL THEREFORE BE APPROPRIATE FOR THE ARROWS DRAWN. +C +C THIS METHOD IS RATHER HEURISTIC AND HAS THREE INHERENT PROBLEMS. +C FIRST, THE CONSTANT 1.E-6 MAY NEED TO BE MADE LARGER OR SMALLER, +C DEPENDING ON THE MAGNITUDE OF YOUR U/V DATA. SECOND, THE NORTH AND +C SOUTH POLES MUST BE AVOIDED. AT EITHER POLE, CFCT GOES TO ZERO, +C GIVING A DIVISION BY ZERO; IN A SMALL REGION NEAR THE POLE, THE +C METHOD MAY TRY TO USE MAPTRN WITH A LATITUDE OUTSIDE THE RANGE +C (-90,+90). THIRD, THE PROJECTION MUST BE SET UP SO AS TO AVOID +C HAVING VECTOR BASEPOINTS AT THE EXACT EDGE OF THE MAP. VECTORS +C THERE WILL BE OF THE CORRECT LENGTH, BUT THEY MAY BE DRAWN IN THE +C WRONG DIRECTION (WHEN THE PROJECTED PARTICLE TRACK DETERMINING THE +C DIRECTION CROSSES THE EDGE AND REAPPEARS ELSEWHERE ON THE MAP). +C WITH A LITTLE CARE, THE DESIRED RESULTS MAY BE OBTAINED. +C --------------------------------------------------------------------- +C +C DECLARATIONS - +C + COMMON /VEC1/ ASH ,EXT ,ICTRFG ,ILAB , + + IOFFD ,IOFFM ,ISX ,ISY , + + RMN ,RMX ,SIDE ,SIZE , + + XLT ,YBT ,ZMN ,ZMX +C + COMMON /VEC2/ BIG ,INCX ,INCY +C +C ARGUMENT DIMENSIONS. +C + DIMENSION U(LU,N) ,V(LV,N) ,SPV(2) + CHARACTER*10 LABEL + REAL WIND(4), VIEW(4), IAR(4) +C +C --------------------------------------------------------------------- +C +C INTERNAL PARAMETERS OF VELVCT ARE AS FOLLOWS.
