Hi Dan,
Thanks for getting back to me.
Do you think I could do it using a showFullTooltip() function, in the same
way that can be done in Treemaps?
The trouble with the Overlay approach is that I have to create DIV classes
for the elements, and I already have a page with a lot of containers
carefully balanced together which I would prefer to leave untouched.
Regards,
Nick
