Thanks for your reply, I'll retest this but i think i've already tried this one out. The ready event does get fired each time the graph is drawn. What i've been doing is removing all event bindings to the chart when the user selects something. Then reconnecting them after the chart has fired the 'animationfinish' event.
Doesn't seem to make any difference. I still get a null error. Turning off animations makes everything just fine. Even though i remove the select event handler I still get an error.
