Does anybody know how to zoom a chart (regardless of type) in and out? I'm sure it is simple to do but it is not clear how to do it.

Thanks in advance,
Steve

you can add a slider to your chart and then add a listener or simplily add a listener on your chart which will attribute new value (height and width) to the content panel of your chart when the event type is fire.
for example
*with a slider:
slider.addListener(Events.Change, new Listener<SliderEvent>(){
public void handleEvent(SliderEvent se){
YourContenPanel.setSize(height, width);
}
});

*directly on the chart:
pie.addChartListener(new ChartListener() {

public void chartClick(ChartEvent ce) {
YourContenPanel.setSize(height, width);
}
});

That worked. In particular the zooming of the chart itself appeared to work better in most instances than zoom the ContentPanel which makes sense. I appreciate the help jocy. Thanks again.
