-Show a colormapped xy plot. Requires extra data for the color. zmin/zmax can be
-used to set the extents of the colors. Automatically sets the
-C<--rangesize>/C<--tuplesize>.
+This is a legacy option used to who a colormapped xy plot. It does:
+
+- Adds C<palette> to C<--curvestyleall>
+
+- Adds 1 to the default C<--tuplesize> (if C<--tuplesizeall> is not given
+
+- Uses C<--zmin>, C<--zmax> to set the colorbar range
+
+It's clearer to set the relevant options explicitly, but C<--colormap> still

Dima Kogan	96ac271cda	I explicitly ignore all lines that have '-' values These may come from vnl-filter -p "dx=diff(x)" ... output. For instance, this plot is broken before this patch: (echo '# x'; seq 5) \| vnl-filter --noskipempty -p 'd=diff(x)' \ \| feedgnuplot --lines	2024-01-27 17:01:40 -08:00

Dima Kogan	8c0f3df285	Added --cbmin, --cbmax These are used unless --colormap. Added more docs to describe what --colormap does. It is legacy.	2022-03-02 19:38:44 -08:00
Dima Kogan	c99b377083	--zmin,--zmax,--zlabel are sent if requested I don't try to figure out if they make sense or not: gnuplot can do that	2022-03-02 19:32:19 -08:00
