I fixed the problem now, the page is cleared now if you use plclear()  
and do a consecutive replot/remake. This was actually not a problem of  
the wxWidgets driver, but of the plot buffer (which took me a while to  
sort out). Anyway, this solution might also be not optimal since the  
plot buffer is not cleared - if you replot the whole (old) plot will  
be plotted which is cleared at the end :). But I also did some other  
improvements, so you might try out the latest svn revision.

One solution would be to clear the plot buffer for such a command, but  
this is problematic, since not everything should be cleared I think,  
this has to be checked and tested. On the other hand it may be better  
to stick with pladv(0) and sort out the increasing memory consumption.  
At least plcear() does now what it should do even if it does it not  
"optimal".

Thanks for the report.

Regards,
Werner
