Gnuplot is a commandline 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 3d coordinate space, or as a
contour plot on the xy plane. For 2d 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 commandline editing and history
on most platforms.
 gpt35exe.zip contains two MSDOS executables: a standard 8086
executable and the other which requires a card with a VESA driver.
 gpt35win.zip contains the necessary files for a MS Windows
version of Gnuplot.
 gpt35src.zip contains the source code for various platforms
including MSDOS, MS Windows and OS/2.
 gpt35doc.zip contains the documentation.
