| Gnuplot 4.0 - Visualize mathematical
functions and data. Gnuplot is
a portable command-line driven
interactive datafile (text or
binary) and function plotting
utility for UNIX, IBM OS/2, MS
Windows, DOS, Apple Macintosh,
VMS, Atari and many other
platforms. The software is
copyrighted but freely
distributed (i.e., you dont
have to pay for it). It was
originally intended as
graphical program which would
allow scientists and students
to visualize mathematical
functions and data. It does
this job pretty well, and in
addition it serves as
non-interactive plotting
engine for miscellaneous
portable third-party
applications, like Octave.
Gnuplot is developed and
supported since 1986, and
having its scripts and
commands easy to understand
text files, it is
time-portable as well. Gnuplot
supports various kinds of
plots. In 2D, it can draw
line, point, dot, box,
histogram graphs or vector
fields. In 3D, it supports
line, point and dot surfaces,
with or without hidden line
removal. It supports color or
grayscale surfaces and maps,
even for non-equidistant and
non-rectangular 3D data,
otherwise it offers data
gridding. Gnuplot supports
many different types of
terminals: interactive screen
terminals (with mouse and
hotkey functionality), pen
plotters (like hpgl), printers
(including postscript and many
color devices), and printings
to output file as vectorial
pseudo-devices like LaTeX,
metafont, pdf, svg, or bitmap
png. Gnuplot is easily
extensible to include new
devices. |
