I've placed two files in the grass/incoming directory on the moon:
graph.README which is partly reproduced below, and graph.tar.Z.
If you get/test this stuff I would like to know if you have any comments.
As Craig Anderson suggested a couple of days ago, I'll keep a log of
responses to find out if there is a potential need for things like this.
graph.README (Wed Oct 6 23:37:35 MET 1993)
The file graph.tar.Z contains two shell scripts to extend the graph
plotting capabilities of GRASS. They are basically frontends for
gnuplot (or g.gnuplot). If you don't have <g.>gnuplot installed (see
below), they won't work.
- r.hplot.sh produces a histogram of the cell values from a single
raster map. Gnuplot needs to have the `boxes' plotting capability
(version 3.4 and later).
- r.splot.sh produces a bivariate scatterplot of the cell data from two
raster maps. (Works with older gnuplot versions as well.)
I have tested these scripts on a sun4 (SunOs 4.1.1, /bin/sh). Partial
testing (without running the GRASS commands) succeeded on an i386/387
equiped with NetBSD 0.9 (/bin/ash, gawk).

Consider it experimental GPL-ed stuff that comes ``as is''. If you find
these programs useful contributions to GRASS, find bugs, have comments,
ideas for enhancement, etc., please e-mail to <venn@geo.vu.nl>. .....
