 Note.									
 The line width of unlabeled contours is designed as a quarter of that	
 of labeled contours. 							

 All color specifications may also be made in X Window style Hex format
 example:   axescolor=#255						

 type:   sudoc pscontour    for more information			


Notes:

 For nice even-numbered contours, use the parameters  fc and dc

 Example: if the range of the z values of a data set range between
 approximately -1000 and +1000, then use fc=-1000 nc=10 and dc=100
 to get contours spaced by even 100's.
