Brilliant! Thanks very much. That sped up the process greatly (and solved the title redraw issue too!). DG is still
faster but the 20second wait for NG that I whinged about in my original post is now a *much* less noticeable
large-fraction of a second.

All of the plot examples in the docs I looked at simply used OVERPLOT -- I didn't see any examples using the refresh
method (until I clicked on the method documentation itself after reading your post. D'oh!)

Merci beaucoup!

cheers,
