RE: [flexcoders] chart data change events

When the dataprovider changes, each series's protected dataChanged
function gets called.

Also, you could access the chart's dataProvider as a ICollection and add
an event listener to it to keep track of the data changes.

Subject: [flexcoders] chart data change events

 

I need to capture an event for when the data is updated in a chart. I
take a snapshot of the 
chart and save it to a file. But when I do it via a custom event which I
fire myself, it fires the 
event and takes the screenshot before the update and so just snapshots
the previous state of 
the chart. And if I use FlexEvent.UPDATE_COMPLETE, it doesn't register a
change since what 
I am doing is adding data to the array which is the dataProvider for the
chart. I can't put an 
update event listener to the array itself since the array does not have
any way to reference 
back to it's chart. 

Any help would be greatly appreciated
