void |
pointSelected(PointSelectionEvent evt)
Called when an attempt has been made to select a point, usually by clicking on a plot. |
Method Detail |
---|
void pointSelected(PointSelectionEvent evt)
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.
evt
- selection event
