There is a package called PLPLOT, available from AMIGA source and binary
archives (comp.sources.amiga, comp.binaries.amiga). It was based on
on Tim Pearsons VAX/Fortran-77 package PGPLOT (from Caltech?) which sees
quite a bit of use for scientific plotting. It was very easy to get
this running on non-AMIGA machines.

I wrote XLIB and POSTSCRIPT level drivers for this,
and use it as a sharable library to call from programs.
Technically, in terms of plotting technique and
capability it is superior to gnuplot, and xgraph-11. It has
2d, 3d, and contour plotting capability.
For an interactive interface I've used the SIOD scheme interpreter.

If somebody would help me with the XMAKEFILE and other considerations
it would could make a worthy X contributed package.

Since it is program callable and encapsulates its state in a few
data structures it isn't too far away from being widget-worthy either.
(I have a list of all internal state variables because of the sharable
library considerations).
