Thank you David and Liam!

I found both of your answers useful. I am going to keep David's
answer in my back pocket until I decide to take the time to learn how
to use pixmap windows. I used Liam's idea, modified of course, but it
worked. I made the first plot, using "plot", then succesive plots
were done using oplot in a 2 step fashion. First I overplotted the
previous plot with the background color, then plotted the next array
using the forground color. Not very elegant, but simple, and it was
fast enough that I had to put wait statements in to slow the animation
down.

Thanks again,
Shawn
