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

[Werner S. <sm...@ia...>]

Hi Robert,

I can duplicate this bug/feature here on Mac OS X with the latest  
PLplot revision. You could use

	pls->adv(0);

instead of the clear(); statement. This will clear the plot, since a  
new one is started. I have to to look at the clear function in plplot  
what is supposed to happen.

Regards,
Werner
