CBCGPBaseChartImpl

Detailed Description

The CBCGPBaseChartImpl class implements common algorithms for series drawing. Each series maintains a pointer to its specific "implementation". For example, CBCGPChartLineSeries contains a pointer to CBCGPLineChartImpl, CBCGPChartBarSeries - CBCGPBarChartImpl, etc.

If you need to customize a specific implementation, derive a class from CBCGP[chart_type]ChartImpl and call CBCGPChartSeries::SetChartImpl. The corresponding implementation is created by CBCGPChartSeries::OnCreateChartImpl, which also can be overridden. Note, that a pointer to implementation is deleted automatically by series.

Inherits CObject.

Inherited by CBCGPAreaChartImpl, CBCGPBarChartImpl, CBCGPBoxPlotChartImpl, CBCGPBubbleChartImpl, CBCGPLineChartImpl, CBCGPLongDataChartImpl, CBCGPPercentChartImpl, and CBCGPSurfaceChart3DImpl.
