Gnuplot is a portable multi-platform command-line driven graphing utility.
It was originally created to allow scientists and students to visualize
mathematical functions and data interactively, but has grown to support
many non-interactive uses such as web scripting. It is also used as a
plotting engine by third-party applications like Octave. Gnuplot has been
supported and under active development since 1986.
Gnuplot supports many types of plots in either 2D or 3D. It can draw using
lines, points, boxes, contours, vector fields, surfaces, and various
associated text. It also supports various specialized plot types. Gnuplot
supports many different types of output: interactive screen terminals
(with mouse and hotkey input), direct output to pen plotters or modern
printers, and output to many file formats (eps, emf, fig, jpeg, LaTeX,
pdf, png, postscript, ...). Gnuplot is easily extensible to include new
output modes. Recent additions include interactive terminals based on
wxWidgets (usable on multiple platforms), and Qt. Mouseable plots embedded
in web pages can be generated using the svg or HTML5 canvas terminal
drivers.
