// CaptureClickEvents:
// You can capture click events on the Gantt bars to get the
// data assciated with the bar. To capture click events,
// - Register a GraphActionListener with the chart so the chart is
// notified when the user clicks on a data element (Gantt bar)
// - In the GraphActionListener, create a PickInfo object
// to get the data associated with a clicked bar
// - Extract data as needed from the PickInfo object
