NAME
pltpar -- Edit the parameter set that describes axis attributes.
.ih
USAGE
pltpar
.ih
DESCRIPTION
The 'axispar' parameters specify the attributes of plot axes.

Note that this is a pset, not an executable task;  it defines a set of 
parameters used by other tasks.  Invoking the pset by name runs
'eparam' on the parameter set, allowing the user to modify the
parameters.  Alternatively, the parameters may be modified on the
command line by specifying the pset name and parameter name, for
example, the user can type "pltpar.pointmode=yes" to set only the
'pointmode' parameter.  Parameters can also be edited by using
'eparam' on the calling task (e.g., by typing "eparam sgraph"), in 
which case, 'pltpar' will appear as one of the task parameters; the
'pltpar' parameters may then be edited by positioning the cursor on
the line containing the pset name and typing ":e".  After editing
the pset parameters, type Control-Z (or ":q") 
to return to the main task parameter menu.

PARAMETERS
.ls (wl = 0.) [real]
Left world X-coordinate if not autoscaling.
.le
.ls (wr = 0.) [real]
Right world X-coordinate if not autoscaling.
.le
.ls (wb = 0.) [real]
Lower world Y-coordinate if not autoscaling.
.le
.ls (wt = 0.) [real]
Upper world Y-coordinate if not autoscaling.
.le
.ls (xflip = no) [boolean]
Flip the autoscaled X axis?
.le
.ls (yflip = no) [boolean]
Flip the autoscaled Y axis?
.le
.ls (transpose = no) [boolean]
Transpose the X and Y axes of the plot?  If 'transpose = no', the
horizontal axis will have the X values or pixel number.
.le
.ls (logx = no) [boolean]
Scale the X axis logarithmically?
.le
.ls (logy = no) [boolean]
Scale the Y axis logarithmically?
.le
.ls (rejectlog = yes) [boolean]
Replace invalid logarithmic values with 'INDEF'?  Invalid values will
be ignored in scaling and plotting.
.le
.ls (box = yes) [boolean]
Draw the box containing the axes and labels around the edge of the
window?
.le
.ls (ticklabels = yes) [boolean]
Label major tick marks?
.le
.ls (grid = no) [boolean]
Draw grid lines on the plot?
.le
.ls (xlabel) [string]
X-axis label.
.le
.ls (ylabel) [string]
Y-axis label.
.le
.ls (title = imtitle) [string]
The plot title may consist of one or two lines of text.  If the
parameter 'sysid' is set to "yes", then the first line of the title is
a standard system-supplied string containing the user's name, date,
etc.  If the 'title' parameter contains the string "imtitle" (the
default), then the plot title will contain a line made up from the
input file, image, or table name.  The user can supply an optional
string for the 'title' parameter--this string will replace the string
resulting from the "imtitle" specification.
.le
.ls (sysid = yes) [boolean]
Include standard system information in the plot title?  If the 'sysid'
parameter is "yes", then a string including the user's name, date, host
name, etc. is included in the plot title.
.le
.ls (lintran = no) [boolean]
Perform a linear transformation of the X axis?
.le
.ls (p1 = 0.) [real]
Starting input pixel value if 'lintran = yes'.
.le
.ls (p2 = 0.) [real]
Ending input pixel value if 'lintran = yes'.
.le
.ls (q1 = 0.) [real]
Starting output pixel value if 'lintran = yes'.
.le
.ls (q2 = 1.) [real]
Ending output pixel value if 'lintran = yes'.
.le
.ls (majrx = 5) [integer]
Number of major divisions along the X grid.
.le
.ls (minrx = 5) [integer]
Number of minor divisions along the X grid.
.le
.ls (majry = 5) [integer]
Number of major divisions along the Y grid.
.le
.ls (minry = 5) [integer]
Number of minor divisions along the Y grid.
.le
.ls (round = no) [boolean]
Round axes to nice values?  (Values at tick marks will be significant,
based on scale of the data.)
.le
.ls (margin = INDEF) [real, min = 0, max = 1]
The margin between the viewport edges (plot axes) and the limits of the
plotted curve(s) as a fraction of the viewport (NDC).  If 'margin =
INDEF', the default, a 2.5% margin will apply.  That is, the plotted
curve(s) will be inset .025 times the size of the viewport.  Set
'margin = 0' to plot curves to the axes.
.le
.ls (version = 17August92) [string]
Date the task was installed.  This should not be changed by the user.
