Given a chart data returns a screen point in chart's owner client coordinates.

This method can be called to convert ChartData (which can be extracted from a data point) to a screen point in chart owner's client coordinates.

You can call CBCGPChartAxis::PointFromValue to convert a specific value to a screen coordinate (X or Y, depending on axis orientation).
