Detailed Description

a basic plot widget.

Can plot only one curve. the axis limits can be set or calculated automatically.

The contrib/plot stuff shipped with wxWidgets has a very strange behaviour and design. I can't think of a situtation where using it can be used...

This based on code I recycled from some university assignment I wrote several years ago.
