Question

这是我的数组集合

 [Bindable]private var Projects:ArrayCollection = new ArrayCollection( [
                { Department: "Software", TotalProjects: 73,Completed:30,Inprogress:30,Approved:13},
                { Department: "XML",TotalProjects: 50,Completed:20,Inprogress:20,Approved:10},
                { Department: "Publishing",TotalProjects: 25,Completed:5,Inprogress:10,Approved:10},
                { Department: "Indesign", TotalProjects: 70,Completed:30,Inprogress:30,Approved:10},
                { Department: "Imaging", TotalProjects: 42,Completed:30,Inprogress:10,Approved:2}]);

折线图系列：

<mx:series>


<mx:LineSeries id="cs1"
                                   yField="TotalProjects"
                                   xField="Department"
                                   displayName="TotalProjects">

                </mx:LineSeries>
                <mx:LineSeries id="cs2"
                               yField="Inprogress"
                               xField="Department"
                               displayName="Inprogress">

                </mx:LineSeries>
                <mx:LineSeries id="cs3"
                               yField="Completed"
                               xField="Department"
                               displayName="Completed">

                </mx:LineSeries>
                <mx:LineSeries id="cs4"
                               yField="Approved"
                               xField="Department"
                               displayName="Approved">

                </mx:LineSeries>


            </mx:series>

如何根据数组集合值动态创建mx:LineSeries。现在只有4个系列，但有些时候我必须根据数组集合值显示更多更改ex：如果还有一个状态HoldProject添加到数组集合中吗？

Answer 1

var series:Array=[];
for (var prop:String in Projects[0])
    if (prop != "Department") {
        var ls:LineSeries=new LineSeries();
        ls.yField=prop;
        ls.xField="Department";
        s.displayName=prop;
        series.push(ls);
    }
myChart.series=series;

在这种情况下，dataProvider中的每个项目都应具有相同的属性集。
