I have gotten that far the calculations take so long the rendering speed is
not too important. I have been working on this and I got the subtitle to
animate. My current problem involves the colorbar. When I update the contour
graph and the titles the written over cleanly, but when the colorbar is
redrawn it draws a second one right next to it. Reading other threads I
tried the clf command but the makes the animation kludgy and it has to
reshrink all of the graphs and such.
