Howdy,
This all depends on your definition of embedded
here are the options
1: Generate the graph as an image and insert the image into an image
control.
2: Insert the image into a rich text control (if using web enabled forms on
2007)
3: Final option is to use the Excel ActiveX controls in your form, I've had
a very brief look at this and it is possible although there is a learning
curve to endure
hope this helps
cheers
Ben
