  Some people already kindly offer to help you directly. But for you and other
interested people, I can add some advices to found informations and tutorials
on the Web (I thought that I already did it in the past, but I didn't succeed
to found the message in the archives...)

  The reference manual is the "PostScript Language Reference, The Red Book",
Third Edition (912 pages, Addison-Wesley, 1999; ISBN 0201379228). It is
available on line ( http://www.adobe.com/print/postscript/pdfs/PLRM.pdf ),
but printing a 912 pages book will be more expensive that buying it!

  Nevertheless, just for plotting functions with `pst-plot', you will need
a small fraction of the language. Using the examples you will have and
refering to some online tutorials must be enough.

  For instance, look at:
http://gamba.math.ubc.ca/localdoc/Flat/math.html
http://gamba.math.ubc.ca/localdoc/Flat/math-ref.html

  The whole tutorial is on:
http://gamba.math.ubc.ca/localdoc/Flat/PS-toc.html

  Of course, you could find other ones. A good list of resources on PostScript
could be found on:
http://www.geocities.com/SiliconValley/5682/postscript.html
and for using PostScript as a programming language on a dedicated page on it:
