I am using ArcMap to build a thematic map. (Layer Properties - Symbology - Proportional symbols)
But I don't know how arcmap calculate the size of symbol in the lengend in TOC.
Can VBA (with arcObject) customize the way the legend appear?
how do proportional symbols appear in the legend?

Thank you for your link.
i found that the size in points is proportional to the square root of the data values
Normal case:
Pj = (Valj/ValMin)^0.5 * Pmin
in case, i want to change the square root to another functions. Ex: log10, cube root...
Using ArcObject can do this?
I'm in a hurry.
Many thanks!
