Graduated Symbols

Question

How do you created an IClassBreaksRenderer that uses "Graduated Symbols"?

I have been able to create one for "Graduated Colors" but have not found the way to programmatically modify this setting.

Thanks
Mike

Glad you got it working. That ILegendInfo class can be confusing because it controls the appearance of layers in the TOC and their renderer in the symbology tab. Don't forget to mark this thread as answered.

Adding the following seemed to have fixed my issue ...

IClassBreaksRenderer renderer = new ClassBreaksRendererClass();
ILegendInfo li = (ILegendInfo)renderer;
li.SymbolsAreGraduated = true;

Thanks Rich.
You helped me out a lot.

The layer symbology properties dialog now opens with the Graduated Symbols item selected.

Only the settings that show when Graduated Colors is selected are being honored (map, toc, legend).

Also, when I alternate clicking between the two options, Graduated Colors shows the symbols that I set thru ArcObjects.
Graduated Symbols is randomly picking a color each time i click on it.

Basically, the sizes and symbols are only being applied to the Graduated Colors configuration.
