<DD>Handles a 'click' on the chart.
 <P>
 JFreeChart is not a UI component, so some other object (e.g. ChartPanel)
 needs to capture the click event and pass it onto the JFreeChart object.
 If you are not using JFreeChart in a client application, then this
 method is not required (and hopefully it doesn't get in the way).
