function LegendToValueIndex(LegendIndex: Integer): Integer; override;

Description
Special internal function.
Returns the value index that corresponds to the LegendIndex parameter.

As Pie series slices can "grouped" ( see PieSeries OtherSlice property ), it might happen the Legend items do not correspond linearly to the Series value indexes.
