Plotxyz-A versatile 2D and 3D graphic program
Plotxyz is an extension of an earlier program
called plotxy that existed on the internet
in the 80's. It keeps the very efficient
scripting language of plotxy and extends
its capabilities into 2D contours and 3D
surface plots. It also has more controls
than the original plotxy, such as line thickness,
fonts, etc, since it is essentially reimplemented
using a postscript package PSLIB.
The entire package can be downloaded here.
After downloading the file plotxyz.tar.gz, unpack it by "tar -zxpvf plotxyz.tar.gz" and a directory called "plotxyz" will be created. Do this: Go to plotxyz/PSLIB and type "make"; Go to plotxyz/plotxy and type "make", and that is it. The executable is called pltxyz in plotxyz/plotxy dircetory.
The original plotxy manual is here in Postscript and here in PDF. Read this first.
