Well, that wouldn't animate the plot, really. Just
show more and more data piled on top of it.

Try this. Create a pixmap window the same size
as your display window. Draw your plots in the
pixmap window, then use the DEVICE COPY technique
to copy the contents of the pixmap window to the
display window. This will result in a flicker-free
animation. :-)

Cheers,

David
