    • Method Detail

      • pointSelected

        void pointSelected​(PointSelectionEvent evt)
        Called when an attempt has been made to select a point, usually by clicking on a plot. The selection event is triggered by the attempt; the content of the event indicates whether any point(s) were actually selected.

        Note that because identification of a selected point is a potentially expensive operation (it requires a scan of all plotted data points), this method is called asynchronously, rather than from the associated mouse listener. Invocation will however be on the Event Dispatch Thread as usual.

        Parameters:
        evt - selection event
