[comp.sources.wanted] Need PostScript code for fancy algebraic graphing

antony@lbl-csam.arpa (Antony A. Courtney) (10/26/89)

I am writing a program to handle some fairly complex graphing problems for my
Calculus course.  I would like to have the program essentially write a
PostScript program to do the graphing.  If anyone has some sample PostScript
code which draws a graph in a fairly efficient manner, I'd appreciate it.
(By efficient, I mean that for any curve, I'd rather not do a table of
values type approach, but rather have any algorithm where if I know a few
points, the curve will be drawn THROUGH those points(I notice with splines
the points are often missed.) )

		Thanks!
