public class IlvChartZoomAction extends IlvChartAction
IlvChartZoomAction
is created, it registers an
internal, private event listener with the chart axis so that the action
can automatically enable and disable itself appropriately. If, at a later
time, you want to remove the action from the user interface and have it
garbage-collected, you will need to explicitly call its IlvChartAction.setChart(ilog.views.chart.IlvChart)
method with a null
argument to detach the action from the chart, hence
removing itself from the listener list.changeSupport, enabled
