Thanks for the quick reply.  Alan's suggestion does
indeed work.  For documentary completeness, wxPlot
overrides plPlot->col, so that 
plPlot->col( PLINT ) => col0 
and plPlot->col( PLFLT ) =>col1

As for the speed, I was expecting that a function call
such as:
myPlot->poin( NUM_POINTS, x, y, 1 )

would be faster than calling poin() individually on
each point.  I think that wxWidgets does do a screen
update on each call to myPlot->poin(), and this slows
things down a bit (I'm graphing ~O(10^5)). 
Nonetheless, the overhead is certainly acceptable for
my purposes, if not ideal.

Thanks again for the help.

Sinerely,
Fred
