Have you tried using the echo command to pipe variables and characters to d.text for user defined labels and ticks? It takes some work with the at=x,y coords to get the legend, labels and ticks where you want them.
echo "message" | d.text size=3 at=37,25 color=orange To erase map elements or labels, you can echo dummy characters the same color as the background: echo "##########" | d.text -b size=5 at=18,6 color=white You may also want to use a graphics tool (e.g, ImageMagick, convert) to do various graphics conversions on the maps.
