CoClasses that implement ICalcRendererValues

CoClasses and Classes Description
CalcRendererValues An object that calculates renderer statistics which are required for some uses of the ChartRenderer object.

Remarks

When setting up a ChartRenderer  with charts that either vary in size, or that use normalization by percent of total, you can use a CalcRendererValues object to calculate some statistics that you set to the chart symbol and renderer so that: 1) the charts appear correctly on the map, and 2) and the chart legend information is correct
