[Plplot-general] How to clear/reset a plot in the wxWidgets driver?

[Robert P. <rob...@jk...>]

Hello Werner,

I am just trying to clear a plot to prepare plotting of a modified diagram.

How is this done? When I try it as follows, the plot window is not
cleared, and the new title text superimposes the old one instead.

Best regards,
Robert
