SYNOPSIS
SEISMIC UNIX NOTES PSWIGP - PostScript WIGgle-trace plot of f(x1,x2) via Polygons
Best for few traces. Use PSWIGB (Bitmap version) for many traces.
pswigp n1= [optional parameters] <binaryfile >postscriptfile
Required Parameters:
n1 number of samples in 1st (fast) dimension
Optional Parameters:
d1=1.0 sampling interval in 1st dimension
f1=0.0 first sample in 1st dimension
n2=all number of samples in 2nd (slow) dimension
d2=1.0 sampling interval in 2nd dimension
f2=0.0 first sample in 2nd dimension
x2=f2,f2+d2,... array of sampled values in 2nd dimension
bias=0.0 data value corresponding to location along axis 2
perc=100.0 percentile for determining clip
clip=(perc percentile) data values < bias+clip and > bias-clip are clipped
xcur=1.0 wiggle excursion in traces corresponding to clip
fill=1 =0 for no fill;
>0 for pos. fill;
<0 for neg. fill
=2 for pos. fill solid, neg. fill grey
=-2for neg. fill solid, pos. fill grey
SHADING: 2<=abs(fill)<=5 2=lightgrey 5=black
linewidth=1.0 linewidth in points (0.0 for thinest visible line)
tracecolor=black color of traces; should contrast with background
backcolor=none color of background; none means no background
verbose=1 =1 for info printed on stderr (0 for no info)
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=seismic normal (axis 1 horizontal, axis 2 vertical) or
seismic (axis 1 vertical, axis 2 horizontal)
curve=curve1,curve2,... file(s) containing points to draw curve(s)
npair=n1,n2,n2,... number(s) of pairs in each file
curvecolor=black,.. color of curve(s)
curvewidth=axeswidth width (in points) of curve(s)
curvedash=0 solid curve(s), dash indices 1,...,11 produce
curve(s) with various dash styles
Note: linewidth=0.0 produces the thinest possible line on the output.
device. Thus the result is device-dependent, put generally looks the
best for seismic traces.
The curve file is an ascii file with the points specified as x1 x2 pairs,
one pair to a line. A "vector" of curve files and curve colors may
be specified as curvefile=file1,file2,etc. and similarly
curvecolor=color1,color2,etc, and the number of pairs of values
in each file as npair=npair1,npair2,... .
All color specifications may also be made in X Window style Hex format
example: axescolor=#255
