PSWIGB - PostScript WIGgle-trace plot of f(x1,x2) via Bitmap
Best for many traces. Use PSWIGP (Polygon version) for few traces.
pswigb n1= [optional parameters] 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
wt=1 =0 for no wiggle-trace; =1 for wiggle-trace
va=1 =0 for no variable-area; =1 for variable-area fill
=2 for variable area, solid/grey fill
SHADING: 2<= va <=5 va=2 lightgrey, va=5 black",
nbpi=72 number of bits per inch at which to rasterize
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)
interp=0 no display interpolation
=1 use 8 point sinc interpolation
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)
Notes:
The interp option may be useful for high nbpi values, however, it
tacitly assumes that the data are purely oscillatory. Non-oscillatory
data will not be represented correctly when this option is set.
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
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
