 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.

 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.
