Calls the UI delegate's Paint
method, if the UI delegate is non-null.
PaintEventArgs
with the Graphics
property for painting the chart. 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.
