[mapserver-users] RE [Polluriel potentiel] Re: proportional circle legend

[Steve.Toutant at inspq.qc.ca]

I tried that also.
Using offset works when you know the size of the other classes. With the 
method described earlier I got a legned like this

Many thanks for your time and help

[Polluriel potentiel]  Re: [mapserver-users] proportional circle legend








Ok, I couldn't resist  . . .

http://gis.ci.stpaul.mn.us/datasets/DB/SAINT_PAUL/PUBLIC_WORKS/AVL/DEV/spec_sym_test_public.map?mapext=509450%20119950%20630550%20190050&mapsize=1211%20701&mode=legend&searchmap=true&


ran into a problem with placing text on these.  I tried all sorts of 
permutations of using LABEL to add to this for the three different sizes. 
I tried with a single label, separate labels, etc.  Anyone got 
suggestions?

Hi Steve,

I think your best would be to set a KEYIMAGE in your CLASS:
