Hi, I have 8 charts in 8 separate chart controls. When the user zooms in the first chart (data zoom tool) I want to update the view ranges of all the other charts. I am not sure which event I need to catch that tells me that the zoom operation is done and the first chart is updated. Right now I am catching the mouse up event and use a timer to update the other charts. This works, but it doesn't seem to be the right way to do this.

I'd appreciate any help.

Thanks

Dieter
