get the following run time error when my mouse rolls over one of my charts:
ReferenceError: Error #1069: Property hitData not found on mx.charts.HitData
and there is no default value.
at Chart1/::formatDataTip()
at mx.charts.chartClasses::ChartBase/::invokeDTFunction()
at mx.charts::HitData/get displayText()
at mx.charts.chartClasses::DataTip/set data()
at mx.charts.chartClasses::ChartBase/::updateDataTipToMatchHitSet()
at mx.charts.chartClasses::ChartBase/::processRollEvents()
at mx.charts.chartClasses::ChartBase/::mouseMoveHandler()
Here is the section of code i believe is causing the error:
private function formatDataTip(obj : Object) : String {
var name : String = obj.hitData.item.Publication;
var revenue:Number = obj.hitData.item.Size;
return "<b>Publication: "+name+"</b><br>Size: "+ revenue;
}
