The GNU plotutils package contains software for both programmers 
and technical users. Its centerpiece is libplot, a powerful C/C++ 
function library for exporting 2-D vector graphics in many file 
formats, both vector and raster. It can also do vector graphics 
animations.

libplot is device-independent in the sense that its API 
(application programming interface) does not depend on the type of 
graphics file to be exported.

Besides libplot, the package contains command-line programs for 
plotting scientific data. Many of them use libplot to export 
graphics.

Other ./configure options that you may want to add (provided you install 
the required fonts):

--enable-ps-fonts-in-pcl   enable use of PS fonts in PCL and HP-GL/2 output
--enable-lj-fonts-in-ps    enable use of LaserJet fonts in PS output
--enable-lj-fonts-in-x     enable use of LaserJet fonts on X displays

This package can be useful for managing GNU Metafile plots, used by
default in applications such as ng-spice.
