Hi Bill,

Any suggestions (including where I should post this question) would be
greatly appreciated.

When you say "The MS Chart Control", is that MSGraph, or the Office Web
Component?

If the latter, you could try public.office.developer.web.components. If
it's MSGraph, try microsoft.public.access or
microsoft.public.powerpoint, but as this is on a .Net form, you're best
bet is probably microsoft.public.vsnet.vstools.office.
