Description
The ClipRectangle method creates a Windows GDI clipping region and selects it into

TChart.Canvas device context handle.

The UnClipRectangle method removes any clipping region applied to TChart.Canvas.

You can use this method to avoid Series or custom drawing to go over the desired rectangle

coordinates.

Note: Printing and creating metafiles do not accept clipping regions in logical pixels.
