PLplot is a library of functions that are useful for making scientific
plots. PLplot 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.
