Gri is an open-source language for scientific graphics programming. It is
command-driven, as opposed to point/click. Some users consider Gri similar
to LaTeX, since both provide extensive power as a reward for tolerating a
learning curve. The output is industry-standard PostScript as output,
suitable for inclusion in other documents.
.
Gri can make x-y graphs, contour graphs, and image graphs. Fine control is
provided over all aspects of drawing, e.g. line widths, colors, fonts,
etc. Greek letters and mathematical symbols are available in a TeX-like
syntax.
.
Folks who write 1000-line Gri scripts usually start with something as
simple as the following:
.
open file.dat # open a file
read columns x * y # read the 1st column as x and the 3rd as y
draw curve # draw the data and autoscale the axes
.
A full manual is also available in HTML (gri-html-doc package), in
PostScript suitable for printing (gri-ps-doc package) and on-line by
following links from the gri home page:
