There is no problem in binding a web service to a chart, through a data grid or directly. I do not have an example available right now, but in principle if you take any of the data grid samples provided, you can link a chart compenent to it. 

I'm in preparation for Lotusphere January 2010, Orlando. Part of this preparation includes the use of ILOG charts bound to a Domino web service. Once this stuff is ready I will post it here.

I will be at Lotussphere also

I will try to catch up with you there, if you do not mind

Not at all. Looking forward to meeting you there

Do you know of any samples out there?

I am stuck on this now and need to get this working

never mind my last post, I found a sample on how to do this.

it was burried in a video
