What happens if you move the script tag to the page header? Or at
least directly inside the body element. Also, you might consider
executing JS code after the onload event has triggered instead of
inlining it directly inside the page (which executes immediately). My
guess would be that the problem here is a timing/redraw issue in IE.
So you should really wait until the page is fully loaded before using
PlotKit.
