virtual void CBCGPChartSeries::ClearMinMaxValues ( )

Clears minimum and maximum series values.

The minimum and maximum values (for each component) are automatically calculated when data points are being added to a series.

You can call this method to clear minimum and maximum values and then call RecalcMinMaxValues() when you need to set them again. You can also set custom min and max values using SetMinMaxValues().
