property DelphiCanvas: TCanvas;

Unit
TeeProcs

Description

The DelphiCanvas property returns the original VCL Canvas object that corresponds to the Chart control.

The TeeChart components create a specialized Canvas ( TTeeCanvas3D object ) that
overrides (encapsulates) the original Canvas.
The new Canvas 3D is used to display charts in 3 dimensions and also to maintain
a double-buffered bitmap to avoid screen flicker when redrawing.

The DelphiCanvas property returns the underlying VCL Canvas that is used to display the internal bitmap buffer.

This property can be used to display contents over a Chart without modifying the internal bitmap.

For example, the TChartGalleryPanel component uses the DelphiCanvas property to draw additional "bevel" frames on charts when the mouse passes over a gallery chart.
