Gnuplot is a command-line driven interactive function plotting
utility for UNIX, MSDOS, and VMS platforms. The software is
copyrighted but freely distributed (i.e., you don't have to pay for
it). It was originally intended as graphical program which would
allow scientists and students to visualize mathematical functions
and data. Gnuplot handles both curves (2 dimensions) and surfaces
(3 dimensions). Surfaces can be plotted as a mesh fitting the
specified function, floating in the 3-d coordinate space, or as a
contour plot on the x-y plane. For 2-d plots, there are also many
plot styles, including lines, points, lines with points, error bars,
and impulses (crude bar graphs). Graphs may be labeled with
arbitrary labels and arrows, axes labels, a title, date and time,
and a key. The interface includes command-line editing and history
on most platforms.
