[streetpoet]

dear team, I notice dashboard.xhtml in demo war which has a javascript function 'skinChart', but I don't know
how connect between p:chart and js function 'skinChart'.
Can you tell me what mechanism make p:chart read 'skinChart' function ? thanks a lot.

Resolved. After decompiling the demo source, I found we should use lineModel#setExtender method to set a js function which can be invoke on the page. Thanks.

Yes, you can use setExtender method in a Chart model. Exp; lineModel1.setExtender("skinChart");
