		CBCGPChartSeries *	pInputSeries,
		CBCGPChartValue &	valY1
	)

pure virtual

Calculates Y value for the specifies data point and input series.

This method must be overridden in a derived class and must return a value for the specified by nIndex data point.

If for some reason a value can't be calculated, the method should return an empty CBCGPChartValue object.

Parameters

nIndex	Specifies a zero-based data point index in the input series.
pInputSeries	A pointer to an input series.
valY1	Contains Y1 value when the function returns.
