Gnuplot is a command-line driven interactive function plotting utility for UNIX, MSDOS, and VMS platforms. It was originally intended as graphical program which would allow scientists and students to visualize mathematical functions and data. Gnuplot supports many different types of terminals, plotters, and printers
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.
