PanelChartOnPaint Method
Calls the UI delegate's Paint method, if the UI delegate is non-null.

Namespace: Imsl.Chart2D
Assembly: ImslCS (in ImslCS.dll) Version: 6.5.2.0
Syntax
Copy
protected override void OnPaint(
	PaintEventArgs painteventargs
)

Parameters

painteventargs
Type: System.Windows.FormsPaintEventArgs
The PaintEventArgs with the Graphics property for painting the chart.
Remarks
We pass the delegate a copy of the Graphics object to protect the rest of the Paint code from irrevocable changes (for example, Graphics.translate).

If you override this in a subclass you should not make permanent changes to the passed in Graphics. For example, you should not alter the clip Rectangle or modify the transform. If you need to do these operations you may find it easier to create a new Graphics from the passed in Graphics and manipulate it.

Further, if you do not invoker super's implementation you must honor the opaque property, that is if this component is opaque, you must completely fill in the background in a non-opaque color. If you do not honor the opaque property you will likely see visual artifacts.
