With that many data points, a contouring solution would be
cumbersome - you would have to interpolate using a lot
of points and you would not gain much quality.

If the overhead is still acceptable, so much the better!
On the other hand, a screen update on every graphics 
call seems an exaggeration to me ... but I do not know
anything in particular about wxWorks.
