Flex动态创建多个曲线图+柱形图

获取数据后的回调函数

private function resultHandlerDay(event:ResultEvent):void {
???statisticCount = event.result.statistic.weekstatistic.length;
???var source:ArrayCollection = event.result.statistic.buildingtatistic;
???var seriesArr:Array = new Array();
???for(var i:Number = 0;i<source.length;i++){
???? var columnSeries:ColumnSeries = new ColumnSeries();
??????????????? columnSeries.xField = "statday";
??????????????? columnSeries.yField = "pitchpower"+(i+1);
??????????????? columnSeries.displayName = source[i].buildingname;
??????????????? seriesArr.push(columnSeries);
???}
???if(statisticCount==null){
????myData=null;
???}else{
??????????????? columnCharts.series = seriesArr;
??????????????? columnCharts.dataProvider = event.result.statistic.weekstatistic;
