There are a number of programs which implement CLI and GUI interfaces to the library, as well as APIs for Octave, PERL, Python, TCL, and Yorick. For details, see http://astro.caltech.edu/~tjp/pgplot/ I compiled the library easily under HP-UX, and there are also Linux binary distribution packages for e.g. Debian and Redhat.
