PSWIGP - PostScript WIGgle-trace plot of f(x1,x2) via Polygons
 

 Best for few traces.  Use PSWIGB (Bitmap version) for many traces.

 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

 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

 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)                 

 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.                                  

 Currently, the curve file must have the number of points specified   
 at the top of the file.  This 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
