Occurs immediately after the chart graphic object changes. Write an OnChange event handler to take specific action when the chart graphic changes. The properties of the chart graphic reflect the new settings when OnChange occurs.


For chart graphics that a chart or chart panel creates, you shouldn't assign a handler to this event. The chart or chart panel has already assigned an event handler.
