Custom Data label for Flex 4 Pie Chart

Question

Does anyone know that it is possible if it is possible to create an item renderer for the data labels of a Flex Pie Chart?

i know it is possible to change the formatting of the String using the label function. But i need more control of the way the data label appears.

The background of the label needs to be a a specific color based on the data.

Thank you in advance for any help you may provide

Answer 1

private function pieSeries_labelFunc(item:Object, field:String, index:Number, percentValue:Number):String {
    //process string and return it 
}

in your mxml add this hope this will help

<mx:PieSeries id="pieSeries"
       labelFunction="pieSeries_labelFunc" />
 </mx:series>
