- Gri graphical language
Gri is a GPL-licensed language for scientific graphics programming. The word "language" is important: Gri is command-driven, not point/click.
Some users consider Gri similar to
LaTeX , since both provide extensive power as a reward for tolerating a learning curve.Gri can make
x-y graph s,contour graph s, and image graphs, inPostScript and (someday)SVG formats. Control is provided over all aspects of drawing, e.g. line widths, colors, and fonts. A limitedTeX -like syntax provides common mathematical symbols.Users who write thousand-line Gri scripts usually start with something as simple as the following, which produces an auto-scaled graph.
:open file.dat:read columns x y:draw curve
