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!
