how to set up an accurate bubble plot legend?

Then it suffices to update the values in the attribute table to
relevant values related to your map and to display this 'map' just
like the real one...
thanks for the trick.
One thing that still bothers me with bubble plot is the
lack of the possibility to sort the bubbles so that you are
sure to have the largest in the back...
fillcolor=none and go by outer ring :-/
ISTR some code to sort them was committed somewhere..
I once created a d.vect.chart2  in which I sorted the bubbles, but
never committed it. At this stage, I'd rather implement it in
I see the New York Times often has nice bubble plots for their maps.
They make the fill color semi-transparent, then stacked bubbles are
darker where they overlap. PostScript won't "do" transparency, so
perhaps something to look for in the grass7 display drivers.
Doesn't postscript 3 include transparency ?
But I still think that an option to ordering them should be available.
