(7/31/97, Davis) + +pkg/plot/t_implot.x + The coordinate to be evaluated for dimensions greater than 2 was not + being defined causing an FPE (Dec Alpha) or possible errors on other + platforms. The initialization was added. (4/3/97, Valdes) + +pkg$plot/t_graph.x +pkg$plot/graph.par +pkg$plot/doc/graph.hlp + Added parameters "ltypes" and "colors" to specify a list of line types + and colors when doing multiple data sets. (5/13/96 & 8/21/96, Valdes) + +pkg$plot/t_implot.x + When the vector being plotted was constant the 'l' and 'c' keys selecting + lines/columns from the right plot axis did not work.

(3/27/96, Valdes) + +======= +V2.10.4 +======= + +pkg$plot/t_gkixt.x + Increased the size of the index array from 2048 to 8192 to accomodate + very large metacode files. (3/22/95 MJF) + +pkg$plot/t_implot.x +pkg$plot/pltwcs.x + When trying to plot a column of a 1D image the physical axis was + being set to zero and then used inapproprriately as a pointer offset + causing an error on the Dec Alpha port. The axis now defaults to + 1 and also the task now beeps when attempting a column plot rather + than plotting. (2/16/95, Valdes) + +pkg$plot/t_surface.x + The surface task no longer calls error when the input array is unsuitable + for plotting (constant valued, entirely below floor or above ceiling). + The surf_limits procedure was modified to call eprintf and then return an + error value to the calling program, which terminates the task quietly. + This less drastic error exit will allow [e.g., IRAF test] scripts to + continue after calling SURFACE with an invalid input image. (ShJ 6/23/94) + +pkg$plot/implot.hlp - + This junk copy was deleted. The actual file is doc/implot.hlp. + (2/2/94, Valdes) + +pkg$plot/t_implot.x +pkg$plot/implot.par +pkg$plot/doc/implot.hlp + The step for the j/k keys may now be set by a task parameter. + (2/2/94, Valdes) + +pkg$plot/t_graph.x + The marker sizes were given the wrong sign when inputing the size from + a list. The size must be negative. (8/21/93, Valdes) + +pkg$plot/phistogram.x + Fixed a bug in the way phistogram was binning real data read in from + a list or image that was causing to create one less bin than required + to hold the data. (26/6/93, Davis) + +pkg$plot/phistogram.x + Fixed a bug in the way the the phistogram task was handling input + redirected from the standard input STDIN.

(7/21/92, Valdes) + +======= +V2.10.0 +======= + +======= +V2.10 +======= + +pkg$plot/t_pradprof.x + The new pradprof task was using the file name template expansion routines + instead of the image name template expansion routines producing an error + if the input image name was an image section. (6/23/92, Davis) + +pkg$plot/t_implot.x + There was some ambiguity with the averaging option. This has been defined + that if an averaging size is set then selecting a single line or + column with 'l', 'c', :l, :c will make the selected line be the center + of the averaging region instead of the lower limit. (4/23/92, Valdes) + +pkg$plot/t_pcol.x +pkg$plot/t_implot.x +pkg$plot/t_graph.x +pkg$plot/t_pcols.x +pkg$plot/t_prows.x +pkg$plot/pltwcs.x +pkg$plot/graph.par +pkg$plot/prow.par +pkg$plot/prows.par +pkg$plot/pcol.par +pkg$plot/pcols.par +pkg$plot/doc/graph.hlp +pkg$plot/doc/implot.hlp +pkg$plot/doc/prow.hlp +pkg$plot/doc/prows.hlp +pkg$plot/doc/pcol.hlp +pkg$plot/doc/pcols.hlp + 1. Modified GRAPH, IMPLOT, PROW(S), and PCOL(S) to define and set + a coordinate format in plots. This allows graphs to be + made in DD:MM:SS and related formats. + 2. Modified GRAPH, IMPLOT, PROW(S), and PCOL(S) to use any WCS attribute + coordinate format found in the images. + 3. Added xformat and yformat parameters to GRAPH, PROW(S), and PCOL(S) to + define coordinate plot formats. This allows having a format when a + format attribute in not found in the images, to override a format + attribute, and to allow setting the format in simple text input. + For example, GRAPH can plot formated RA and DEC from a list of + input RA and DEC coordinates. + 4. Added a ":f format" to IMPLOT to allow specifying/overriding the + WCS attribute format. + 5. Added <space> as a key in IMPLOT to print coordinate and pixel + value information: + line=256, column=142, coordinate=13:27:55.6, value=222. + (4/9/92, Valdes) + +pkg$plot/pltwcs.x +pkg$plot/t_prows.x +pkg$plot/t_pcols.x +pkg$plot/t_graph.x + The logical coordinates used for coordinate evaluations when + using an image section were incorrectly set. (3/9/92, Valdes) + +pkg$plot/pltwcs.x +pkg$plot/t_graph.x + Modified plt_wcs to take as input the wcs name in order to + set an appropriate wcs label for the wcs instead of using + the world wcs in all cases. + (3/4/92, Valdes) + +pkg$plot/t_pvector.x + In image pixel buffer column limits were being incorrectly computed + in some cases result in glitches in the output vector. + (12/11/91 Davis) + +pkg/plot/t_graph.x +pkg/plot/graph.par +pkg/plot/doc/graph.hlp + An overplot parameter has been added to allow multiple plots with + different axes and viewports. (10/23/91, Valdes) + +pkg/plot/doc/pvector.hlp + Corrected the examples showing usage the center/theta. Also + added a note to the theta parameter notes explaining that is + set the center must be specified with a certain syntax as shown + in the examples. Reported by Tom Duvall (10/8/91 MJF) + +pkg/plot/crtpict/calchgms.x + Changed the declarations for the variables min_val and max_val in + the procedure crt_user_hgram from int to short. (10/5/91, Davis) + +pkg/plot/phistogram.x + Corrected some type mismatch problems in calls to gset. + (10/3/91 Davis) + +pkg/plot/t_implot.x + The use of overlapping multiple graphics WCS, one for the user and + one for the image columns and rows, would result in erroneous + coordinates using the C key and later =gcur. The task was modified + to have the same functional behaviour but work only with one + graphics WCS. (9/12/91, Valdes) + +pkg/plot/t_prow.x +pkg/plot/t_prows.x +pkg/plot/t_pcol.x +pkg/plot/t_pcols.x +pkg/plot/prow.par +pkg/plot/prows.par +pkg/plot/pcol.par +pkg/plot/pcols.par +pkg/plot/doc/prow.hlp +pkg/plot/doc/prows.hlp +pkg/plot/doc/pcol.hlp +pkg/plot/doc/pcols.hlp + Modified to have a wcs parameter and plot using the specified + wcs. The xlabel parameter includes a special word to select + the WCS label in the image. (9/12/91, Valdes) + +pkg/plot/pradprof.par +pkg/plot/t_pradprof.x +pkg/plot/doc/pradprof.hlp + Pradprof was orignally installed on 8/16/91, but had to be + reinstalled on 8/26/91 after a major disk crash. (8/26/91 LED) + + +pkg/plot/phistogram.par +pkg/plot/phistogram.x +pkg/plot/phminmax.x +pkg/plot/doc/phistogram.hlp + Phistogram was originally installed on 8/14/91, but had to be + reinstalled on 8/26/91 after a major disk crash. (8/26/91 LED) + +pkg/plot/pradprof.par +pkg/plot/t_pradprof.x +pkg/plot/doc/pradprof.hlp + Added a new task pradprof to the plot package. (8/16/91 LED) + +pkg/plot/phistogram.par +pkg/plot/phistogram.x +pkg/plot/phminmax.x +pkg/plot/doc/phistogram.hlp + Added a new task phistogram to the plot package. Phistogram takes + input from either an image or a list and permits full control over + the plotting parameters. The histogram computation is done in + and identical manner to the imhistogram task. (8/14/91 LED) + +pkg/plot/t_implot.x +pkg/plot/t_graph.x +pkg/plot/implot.par +pkg/plot/graph.par +pkg/plot/doc/implot.hlp +pkg/plot/doc/graph.hlp + Added a "wcs" parameter to select using image WCS information for + coordinates and labels. (FV 8/12/91) + +pkg/plot/t_implot.x + Corrected the comment on line 892 (ShJ 8/12/91): + +# IMP_SETPIXELCOORDS -- Set wcs 2 to the pixel coordinate system of the image. +should read +# IMP_SETPIXELCOORDS -- Set wcs 1 to the pixel coordinate system of the image. + ^ +pkg/plot/t_surface.x + Default values for floor and ceiling were changed from 0.0 to INDEF. + The default task behavior is the same, plotting from i_datamin to + i_datamax, but the value of 0.0 is now interpreted as a valid data + value rather than a flag to trigger CONREC's automatic limit algorithm. + At the same time, a coding error that forced you to set both floor + and ceiling (you couldn't set just one or the other) was removed. + (ShJ 8/5/91) + +pkg/plot/t_contour.x + Default values for floor and ceiling were changed from 0.0 to INDEF. + A test was added to detect a constant valued field. A call to + gamove was added before the final gclose, to fix the WCS to the + device. All plotting in the NCAR code is done in NDC space (with + conrec parameter nset = 1). Without the additional call to + gamove, plots drawn with perim- would not report cursor positions + in WCS units, since all plotting had been done in NDC space. (ShJ 8/5) + +pkg/plot/surface.par +pkg/plot/contour.par +pkg/plot/doc/surface.hlp +pkg/plot/doc/contour.hlp + These help and manual pages were modified to reflect the new default + values of floor and ceiling. (ShJ 8/5/91) + +pkg/plot/t_prow[s].x +pkg/plot/t_pcol[s].x + Removed the call to clputi for defining upper limits for the input + row/col number. This was done for two reasons: [1] it duplicated + other code in the task that checks that the input limits are valid + and [2] these tasks could be used with epar when a larger image + is plotted after a smaller image; the smaller image limits remain + in the par file and prevent the user from setting a parameter outside + the range of the smaller image. (ShJ 8/5/91) + +pkg$plot/t_pvector.x + Corrected line #45 which had the wrong number of arguments in a call + to error, resulting in a segmentation violation instead of the intended + error message if the condition being detected occurred. (ShJ 1/25/91) + +pkg$plot/doc/pvector.hlp + Clarified documentation regarding the resampling spacing. (SRo 8/31/90) + +pkg$plot/t_pvector.x + Added checks for wx1/wx2 and wy1/wy2 parameters allow plotting on + an inverse scale when not autoscaling. Suggested by Tetsuo Aoki + at CRL. (MJF 8/9/90) + +pkg$plot/t_surface.x + procedure surf_limits was modified to avoid an arithmetic exception + for images with values entirely above ceiling or below floor. This + modification was coded by Phil Hodge at ST. (ShJ 4/4/90) + +pkg$plot/getdata.x + procedure plt_getdata was completely rewritten to remove the call + to imparse and any built-in dependency on knowledge of image + section notation. (ShJ 4/4/90) + +pkg$plot/t_contour.x, t_surface.x, t_hafton.x + were modified to call plt_getdata with its new calling sequence. + (ShJ 4/4/90) +pkg$plot/t_pcol.x, t_pcols.x +pkg$plot/t_prow.x, t_prows.x + The dependency of these routines on knowledge of image section + notation has been removed. Previously an image section name would + be built using the column limits input by the user. The data are + now extracted from the image with procedure plt_gcols and plt_grows. + Code was also cleaned up to make use of single graphics procedure. + (MJF 4/3/90) + +pkg$plot/doc/pvector.hlp +pkg$plot/t_pvector.x, pvector.par + Implemented output options to PVECTOR task allowing computed + vector to be output as an image or text file (MJF 4/3/90) + +pkg$plot/doc/surface.hlp + Clarified floor and ceiling parmeters in surface manual page. + (ShJ 3/1/90) +pkg$plot/t_gkimos.x + Added a call to flush the gki metacode stream before closing it + when interactive=no. Without this, the stdgraph terminal would + remain in graphics mode when gkimosaic terminated. (ShJ 3/8/89) + +pkg$plot/t_pvector.x + Fixed bug causing vectors near theta=0 to fail. (FV 15/6/89) + +pkg$plot/t_gkimos.x + Duplicate definition of MAX_FRAMES removed. A new option was + added to cursor mode, 'r', to redraw the current screen with any + new parameters that may have been set. Functionally equivalent + to skip -NX*NY and hitting the space bar. + + Error handling is improved. GKIMOSAIC was failing when the + WCSDIR information couldn't be decoded. (ShJ 24/5/89) + +pkg$plot/t_gkixt.x + Added dynamic reallocation of index buffer for metacode files + with more then MAX_FRAMES. (ShJ 24/5/89) + +pkg$plot/t_graph.x + Fixed up setting the marker size when the marker type is either + vertical or horizontal eror bars. Previously, both xsize and + ysize were being set equal to the user indicated size. Now only + the dimension that represents the error gets set; the other + dimension is drawn at NDC size 1.0. (ShJ 24/5/89) + +pkg$plot/t_contour.x + Axes were not being drawn properly when parameter 'perimeter' was + set to no. This was due to a missing nset=-1 statement which has + now been added (line 171). Variable nset is passed in a common + block to the NCAR conrec code. (ShJ 24/5/89) + +pkg$plot/getdata.x, t_contour.x, t_surface.x, t_hafton.x + Added support for subsampling or block averaging of image sections. + The contour, surface and hafton tasks were not doing this correctly. + The mod was coded by Zolt Levay of STScI. (ShJ 18/7/88) + +pkg$plot/vport.x + Changed the value of 'ext' from 0.25 to 0.0625 This is the ratio + of axes lengths beyond which contour will make the output viewport + square. The limit of 1:4 was too restrictive; the limit of 1:16 is + also arbitrary but not as restrictive. This change was also made in + gio$ncarutil/conbd.f; this code is used instead of vport.x when + parameter 'perimeter' = no (which is not the default). (ShJ 10/6/88) + +pkg$plot/initmarker.x + Marker types 'hline', 'vline' and 'diamond' were added to the list + of possible marker types in point mode. (ShJ 24/3/88) + +pkg$plot/initmarker.x +pkg$plot/graph.x + Marker types 'hebar' and 'vebar' were added to the list of possible + marker types in point mode. Parameter 'szmarker' should be set + to 0.0 for the third column of an input list to be interpreted + as marker sizes in WCS units. A duplicate copy of procedure + init_marker existed in graph.x and it has been deleted. (ShJ 23/3/88) + +pkg$plot/vport.x + Modified the viewport setting code to accomodate both landscape + and portrait mode devices when compensating for non-unity aspect + ratios. (e.g., fill=no in contour). Previously, only landscape + mode was considered. This mod suggested by Zolt Levay at STScI. + (ShJ 16/12/87) + + if (aspect_ratio < 1.0) + # Landscape + xdis = xdis * aspect_ratio + else if (aspect_ratio > 1.0) + # Portrait + ydis = ydis / aspect_ratio +------ + +pkg$plot/crtpict/t_crtpict.x +pkg$plot/crtpict/tform_image.x +pkg$plot/crtpict/crtpict.h + Whether or not an annotated perimeter is drawn around the image + portion of a crtpict is now controlled by the cl parameter + 'perimeter'. Default value is yes. (ShJ 20/8/87) + +pkg$plot/crtpict/drawgraph.x +pkg$plot/crtpict/plot_hgrams.x + The crtpict task now prints z1 and z2 (the range of input + intensities mapped to output values) on the final print as + well as to STDOUT. The z1, z2, zmin and zmax values are + now output in `%g' format, not `%.2f' format, which will + prevent truncation to 0.0 of very small values. (SeH 23/4/87) + +pkg$plot/graph.x S. Hammond April 23, 1987 + A bug in the graph task, which prevented users from setting the + window when the values being plotted were very small (1E-7 or so), + has been fixed. The task previously would insist on autoscaling + the y axis in this case. + +pkg$plot/contour.x S. Hammond March 9, 1987 + The NCAR contour task was relinked with libncar to pick up a revision + in procedure STLINE which increased the size of a work array. The + error about "work array overflow in STLINE, picture incomplete" + should be seen much less frequently now, as the buffer which + stores starting points of contours at a given level was increased + in size from 500 to 5000. + +pkg$plot/crtpict/map_image.x S. Hammond March 6, l987 + + This procedure was using an incorrect test for finding images + with no range in the data. It was comparing the difference + between z1 and z2 to EPSILONR; it should have been testing z1 and z2 + for equality. The result of this error was that images containing + only small valued pixels (<= e-8 or so) would be mapped entirely + to a single grey level. The error has been fixed. + +pkg$plot/gkimosaic.x S. Hammond Feb 25, 1987 + + The interactive help facility for task gkimosaic (keystroke '?') + was modified to work properly with the newly installed gio mods for + activating and deactivating workstations. + +pkg$plot/graph.x S. Hammond Feb 25, 1987 + + Task graph would hang when the input file was STDIN, a byproduct of the + recent gio mods for activating and deactivating workstations. This + has been fixed. Another bug was also fixed: the marker size read + from the third column of an input list now controls the marker size + on the plot as described in the graph manual page. + +---------------------------------------------------------------------------- + +From: Hammond Dec 23, 1986 +Task: contour (gio$ncarutil/conrec.f) + + The ncar executable was relinked to pick up a mod to conrec.f + in libncar.a. The polyline width was not being set until after + the first contour line had been drawn, and so the first major + contour line would not be drawn in bold font. + +-------------------------------------------------------------------------- + +From: Hammond Oct 28, 1986 +Task: graph (pkg$plot/graph.x) + + A bug that prevented axes from being drawn properly when the + lower window limit exceeded the upper limit has been fixed. + That is, setting wy1 > wy2 now works. + +_________________________________________________________________________ + +From: Hammond Oct 24, 1986 +Task: crtpict, contour (pkg$plot/perim.x) + + The perimeter drawing procedure has been modified to + calculate the label increments and perimeter spacing + independently in x and y. This was not being done + previously, and images which differ greatly in x and y + dimension would produce unpleasing plots. + +_______________________________________________________________________ + +From: Hammond Jul 21, 1986 +Task: gkimosaic + + An additional interactive command was added to gkimosaic. A + command summary is printed with the keystroke '?'. + +_______________________________________________________________________ + +From: Hammond Jun 25, 1986 +Task: gkimosaic + + Task gkimosaic has been modified to allow interactive browsing + through a metacode file. Keystrokes are available to skip + forward or backward through a file, and to interactively + change the number of plots per page and the rotate and fill + options after each page of plots. See the revised manual page + for a complete description. The WCS information for the individual + plots is preserved for cursor readback. + +________________________________________________________________________ + +From: Hammond Jun 18, 1986 +Task: gkidir, gkiextract + + 1. Long strings in GKI_MFTITLE instructions were causing + memory overwrite errors in tasks gkidir and gkiextract; + the problem has been fixed. + + 2. Tasks gkidir and gkiextract have been modified to filter + out blank frames. +____________________________________________________________________________ + +From: Hammond Jun 12, 1986 +Task: prow, prows, pcol, pcols + + These four tasks have been modified to use the standard parameter + names for window and viewport coordinates within the plot package. + Window (user) coordinates are referred to as wx1, wx2, wy1, and wy1; + viewport (NDC) coordinates are referred to as vx1, vx2, vy1 and + vy2. Default values for these parameters have changed - see + the revised manual pages. A 0 range in window coordinates implies + autoscaling; a 0 range in viewport coordinates indicates automatic + viewport placement by "glabax". + + An additional parameter ("fill") has been added. By default, + the plot drawn will fill the specified device viewport. Setting the + value of fill to "no" means equal numbers of data values in x + and y will occupy equal physical lengths when plotted. That is, + a unity aspect ratio is enforced when fill = no. + +_____________________________________________________________________________ + +From: Hammond Jun 12, 1986 +Task: graph + + Several changes have been made to task graph. + + 1. First, to standardize parameter names within the plot package, + the viewport coordinates are referred to as vx1, vx2, vy1 + and vy2; window coordinates are referred to as wx1, wx2, wy1, + and wy2. Default values for these parameters have changed - see + the revised manual page. A 0 range in window coordinates implies + autoscaling; a 0 range in viewport coordinates indicates automatic + viewport placement by glabax. + + 2. Image templates are now understood in the input list. + + 3. An additional parameter ("fill") has been added. By default, + the plot drawn will fill the specified device viewport. Setting + the value of fill to "no" means equal numbers of data values in x + and y will occupy equal physical lengths when plotted. That is, + a unity aspect ratio is enforced when fill = no. + +________________________________________________________________________ + +From: Hammond Jun 12, 1986 +Task: contour, hafton + +1. To standardize parameter names within the plot package, both these + tasks now refer to the device viewport plotting coordinates + as vx1, vx2, vy1 and vy2. + +__________________________________________________________________________ + +From: Hammond Apr 17, 1986 +Task: gkiextrct + +1. A (boolean == false) construct in source file t_gkiextract.x has been + changed to (! boolean). + +___________________________________________________________________________ + +From: Hammond Mar31, 1986 +Task: crtpict + +1. Crtpict now checks the values returned by the automatic windowing + algorithm (ztrans=auto) to make sure they are not equal. The window + limits, z1 and z2, are equal to each other when there is no range + of intensity in the input image. This was not being checked previously, + and could result in floating divide by zero down the line. + +_________________________________________________________________________ + +From: Rooke Mar27, 1986 +Task: calcomp + +1. Changed default value for parameter LWOVER from "no" to "yes"; users + feel it is more important to get plots out quickly than to have bold + text, axes, and axis labels and ticks. Calcomp line width simulation + in lwtype=ntracing draws each line 5 times for medium quality and 9 + times for high quality. Now must explicitly run CALCOMP standalone + on spooled metacode to get bold text etc. +_________________________________________________________________________ + +From: Hammond Mar19, 1986 +Task: Contour, Surface, Hafton + +1. The string "subsampled image ... being contoured" has been replaced + with "subsampled image ... being plotted". This message is printed + when an image is subsampled rather than block averaged on input. + (The source file changed is plot$get_data.x) +__________________________________________________________________________ + +From: Hammond Mar19, 1986 +Task: gkidir, gkiextract + +1.
