Flex:Chart 设置DataTipFunction

某BarChart: showDataTips="true" dataTipFunction="dataTipFunForQualExpSummary"

tipFunction:

		/** 资格过期摘要图表的dataTipFunction. */
		protected  function dataTipFunForQualExpSummary(hd:HitData):String {
			var curObj:Object = hd.item;
			var curSeries:BarSeries = BarSeries(hd.chartItem.element); // 获得当前的BarSeries
			return curObj.qual + "-" + curSeries.displayName + "\n" + uqStatistics.getUQAs(curSeries.xField, curObj.qualObj).length + RM.getString(BUNDLE_DASHBOARD, "label.piece");
		}

效果:

Flex:获得BarChart中选定的对象及BarSeries <-> Flex: PieChart LabelFunction
