使用labelFunction 直接显示PieChart的信息, 如下代码定义一个PieChart:

其labelFunction:

		/** 过期分布PieChart的LabelFunction.  */
		protected static function labelFunForChartExpDEtail(item:Object, field:String, index:Number, percentValue:Number):String {
			var percentString:String = percentValue.toString().substr(0, 5);
			return UserQualStatistics.getTypeLabel(item.type) + ":" + "\n" + RM.getString(BUNDLE_DASHBOARD, "info.total") + ":" + item.total + "(" + percentString + "%)";
		}

效果:

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:
