GnuPlot
GnuPlot is a versatile command line programme that can generate two- and three-dimensional plots of functions and data. The programme runs on all major computers and operating systems. GnuPlot is a program with a fairly long history, dating back to 1986.
GnuPlot can produce output directly on screen, or in many formats of graphics files, among which PNG, EPS, SVG, JPEG and many others. The programme can be used both interactively and in batch mode using scripts. The programme is well supported and documented. Extensive help can also be found on the Internet.
GnuPlot is used as the plotting engine of GNU Octave.
