Description

NOTE: # I modified d.vect.thematic (see attached file) to put the legend into png file if monitor=none and also to render thematic map into png file if no monitor is running....I ALSO HAVE ONE ENHANCEMENT WISH I WILL OUTLINE IN THE END.... Assuming that you have not started any monitors, it renders to png (starts monitor png1) and outputs to ${map}_thematic.png. Also, if monitor=none, the legend is rendered to ${map}_thematic_leg.png. I don't stop the png1 monitor in case you want to add other display commands - so, if you want to add display commands to the ${map}_thematic.png after d_vect_thematic.sh has run, simply do, for eg.: d.mon sel=png1 d.vect ewstates type=boundary d.mon stop=png1

This will be very useful for shell scripting of grass commands. You may want to streamline the process to make the solution more elegant.

ENHANCEMENT WISH: Currently if you choose themecalc=custom_breaks breakpoints="" colorscheme=custom_gradient - you have the option to use just startcolor and endcolor and let the script grade the colors in between. One would want to use custom colors for each break - supplied as an option or as an external file (RGB values etc.) using the breakpoints specified. This seems like a logical thing to want and should not be difficult to implement ... I will not attempt it as I am sure there are others who will do it better and quicker. Thanks much.

You might want to try the new (and hardly tested) d.thematic.area which is in the grass6 dev branch and in the grass7 branch.
