CBCGPChartBaseEffect

Detailed Description

The CBCGPChartBaseEffect class serves as an abstract base class for various "effects" that can be added to a diagram.

The effects are displayed before series, from CBCGPChartVisualObject::OnDrawDiagram. An example of effect is "interline coloring", when spaces between two lines are filled by predefined color.

To implement a custom effect derive a class from CBCGPChartBaseEffect, override OnCalcScreenPoints() and OnDraw() methods and call CBCGPChartVisualObject::AddChartEffect. You can remove all effects by calling CBCGPChartVisualObject::RemoveAllChartEffects.

Call CBCGPChartBaseEffect::SetVisible to hide an effect.
