Is there an event dispatched when a series is added to a chart in flex?

Question

I want to know when the data has been added to a chart so I can use localToData() to draw on the chart. If I do this immediately after setting the dataProvider the chart has not yet updated, so the the call to localToData will not return the correct values. Is there an event I can subscribe to so I know the chart has drawn the data in the dataProvider?

There is a CollectionChanged event, so you can listen to it. Also, initial data can be fetched using initialize/creationComplete event in the Chart component.

Thanks, I'm not sure that would fire when the collection was assigned to the chart though. – slashnick Mar 22 '10 at 14:56
Sure, it will not. But you can build a setter for a collection for that in your custom chart :) TTT, I don't think that is an elegant solution. – mico Mar 22 '10 at 15:26

The updateComplete event whilst not strictly for this purpose, does fire after the series updateDisplayList method has been called, which is close enough.
