[GRASSLIST:8771] Re: Querying display monitor locations as percent from origin (0,0)?

[Michael Barton]

Eric,

I think d.graph does draw in % of screen from one corner or another.

On the other hand, it might be easier to simply save the monitor display to
a png or tiff file (d.out.file) and add a legend manually using Inkscape or
something similar.
