Description:

PLplot is a library of functions that are useful for making scientific
plots. It can be used from within compiled languages such as C, C++,
FORTRAN and Java, and interactively from interpreted languages such as
Octave, Python, Perl and Tcl.

The PLplot library can be used to create standard X-Y plots, semilog
plots, log-log plots, contour plots, 3D surface plots, mesh plots, bar
charts and pie charts. Multiple graphs (of the same or different
sizes) may be placed on a single page with multiple lines in each
graph.

A variety of output file devices such as PostScript, PNG, JPEG,
LaTeX and others, as well as interactive devices such as xwin,
tk, xterm and Tektronics devices are supported. New devices can
be easily added by writing a small number of device dependent
routines.
