It looks as if when using Ajax data-binding with the new Chart control, and the server returns a 500 error (which happened to me because of a small oversight on my end), the control silently eats the exception and simply renders the outer <div> tag for the Chart control.
I know that the Grid control will, at the very least, pop up a Javascript alert() box if an Ajax request returns a 500. It would be nice if the Chart control did the same. I spent at least 15 minutes trying to figure out why my Chart control wasn't rendering properly, making sure all my syntax was correct against the example on this site. It wasn't until I opened Fiddler and noticed that the Ajax request was returning a 500.
I'm at home now and not at work, so I can't provide an example project right this moment, but I can if one is needed.
