Flex LineChart动态创建曲线

假如后台传到前台的数据格式是：

[
 {time:4,[{name:"技术响应时长",value:50%}],{name:"排除故障时长",value:50%}]},{time:5,value:40%},value:60%}]},{time:6,value:70%},value:30%}]}
]

?

那么前台创建曲线是

protected function getMEMPerfDataResult(event:BusinessManagerEvent):void
			{
				var arrcol:ArrayCollection = event.object as ArrayCollection;
				if(arrcol && arrcol.length>0){
					var dataProvider:ArrayCollection  = new ArrayCollection();
					var timeChartVo:TimeChartVO = arrcol[0] as TimeChartVO;
					 var array:Array = [];
					var lineSeries:LineSeries;
					for (var i:int = 0; i < timeChartVo.series.length; i++) 
					{
						lineSeries = new LineSeries();
						lineSeries.displayName = "物理内存利用率";
						lineSeries.yField="value"+i;
						lineSeries.setStyle("form","curve");  
						lineSeries.setStyle("lineStroke",seriesStrok0);
						/* if(i<7){
							lineSeries.setStyle("lineStroke",seriesStrok0);
						} */
						array.push( lineSeries);
					} 
					
					///// 设置系列数量。
					memoryUsageChart.series = array;
					
					 
					for (i = 0; i < arrcol.length; i++) 
					{
						timeChartVo = arrcol[i] as TimeChartVO;
						var obj:Object = {};
						obj.lineTime = timeChartVo.lineTime;
						for(var j:int = 0;j<timeChartVo.series.length;j++){
							obj["value"+j] = SeriesVO(timeChartVo.series[j]).value;
						}
						dataProvider.addItem(obj);
					} 	
					
					memoryUsageChart.dataProvider = dataProvider;
				}
			}
