[jChartFX toolbar]

Hi, I'm a newbie here. And I would like to ask how can we show the jChartFX toolbar in the chart?

I've tried: 

chart1.getToolBar().setVisible(true);

But I got an error saying:

Object has no method 'getToolBar()'

 Can someone pls help me out here? coz Im pretty convince that this toolbar does exist coz I cams across this line: 

 Scrollbars will appear automatically when the end user uses the Zoom tool available in the jChartFX toolbar

Thank you very much!
