SYNOPSIS
SEISMIC UNIX NOTES PSGRAPH - PostScript GRAPHer
Graphs n[i] pairs of (x,y) coordinates, for i = 1 to nplot.
psgraph n= [optional parameters] <binaryfile >postscriptfile
Required Parameters:
n array containing number of points per plot
Data formats supported:
1.a. x1,y1,x2,y2,...,xn,yn
b. x1,x2,...,xn,y1,y2,...,yn (must set pairs=0)
2. y1,y2,...,yn (must give non-zero d1[]=)
3. x1,x2,...,xn (must give non-zero d2[]=)
4. nil (must give non-zero d1[]= and non-zero d2[]=)
The formats may be repeated and mixed in any order, but if
formats 2-4 are used, the d1 and d2 arrays must be specified including
d1[]=0.0 d2[]=0.0 entries for any internal occurences of format 1.
Similarly, the pairs array must contain place-keeping entries for
plots of formats 2-4 if they are mixed with both formats 1.a and 1.b.
Also, if formats 2-4 are used with non-zero f1[] or f2[] entries, then
the corresponding array(s) must be fully specified including f1[]=0.0
and/or f2[]=0.0 entries for any internal occurences of format 1 or
formats 2-4 where the zero entries are desired.
Available colors are all the common ones and many more. The complete
list of 68 colors is in the file $CWPROOT/src/psplot/basic.c.
Optional Parameters:
nplot=number of n's number of plots
d1=0.0,... x sampling intervals (0.0 if x coordinates input)
f1=0.0,... first x values (not used if x coordinates input)
d2=0.0,... y sampling intervals (0.0 if y coordinates input)
f2=0.0,... first y values (not used if y coordinates input)
pairs=1,... =1 for data pairs in format 1.a, =0 for format 1.b
linewidth=1.0,... line widths (in points) (0.0 for no lines)
linegray=0.0,... line gray levels (black=0.0 to white=1.0)
linecolor=none,... line colors; none means use linegray
Typical use: linecolor=red,yellow,blue,...
lineon=1.0,... length of line segments for dashed lines (in points)
lineoff=0.0,... spacing between dashes (0.0 for solid line)
mark=0,1,2,3,... indices of marks used to represent plotted points
marksize=0.0,0.0,... size of marks (0.0 for no marks)
xbox=1.5 offset in inches of left side of axes box
ybox=1.5 offset in inches of bottom side of axes box
wbox=6.0 width in inches of axes box
hbox=8.0 height in inches of axes box
x1beg=x1min value at which axis 1 begins
x1end=x1max value at which axis 1 ends
d1num=0.0 numbered tic interval on axis 1 (0.0 for automatic)
f1num=x1min first numbered tic on axis 1 (used if d1num not 0.0)
n1tic=1 number of tics per numbered tic on axis 1
grid1=none grid lines on axis 1 - none, dot, dash, or solid
label1= label on axis 1
x2beg=x2min value at which axis 2 begins
x2end=x2max value at which axis 2 ends
d2num=0.0 numbered tic interval on axis 2 (0.0 for automatic)
f2num=x2min first numbered tic on axis 2 (used if d2num not 0.0)
n2tic=1 number of tics per numbered tic on axis 2
grid2=none grid lines on axis 2 - none, dot, dash, or solid
label2= label on axis 2
labelfont=Helvetica font name for axes labels
labelsize=18 font size for axes labels
title= title of plot
titlefont=Helvetica-Bold font name for title
titlesize=24 font size for title
titlecolor=black color of title
axescolor=black color of axes
gridcolor=black color of grid
axeswidth=1 width (in points) of axes
ticwidth=axeswidth width (in points) of tic marks
gridwidth=axeswidth width (in points) of grid lines
style=normal normal (axis 1 horizontal, axis 2 vertical) or
seismic (axis 1 vertical, axis 2 horizontal)
reverse=0 =1 to reverse sequence of plotting curves ", /* JGHACK
Note: n1 and n2 are acceptable aliases for n and nplot, respectively.
mark index:
1. asterisk
2. x-cross
3. open triangle
4. open square
5. open circle
6. solid triangle
7. solid square
8. solid circle
All color specifications may also be made in X Window style Hex format
example: axescolor=#255
Example:
psgraph n=50,100,20 d1=2.5,1,0.33 <datafile >psfile
plots three curves with equally spaced x values in one plot frame
x1-coordinates are x1(i) = f1+i*d1 for i = 1 to n (f1=0 by default)
number of x2's and then x2-coordinates for each curve are read
sequentially from datafile.
