我希望能够动态添加（或删除）列系列。

有没有人知道如何在线进行此操作的教程？

Answer 1

你可以试试这个。

var cs:ColumnSeries=new ColumnSeries();
cs.yField="yourYfield";
cs.xField="yourXfield";
cs.displayName="yourDisplayName";
columnChart.series.push(cs);

您的柱形图

<mx:ColumnChart id="columnChart"/>

Answer 2

尝试以下一个代码......难以理解但易于实现....

arrcolpie=new ArrayCollection();
            for(var i:int=0;i<arrCategoryName.length;i++)
            {
                var temp1:int;
                temp1 = i;

                addElementInCollection(arrCategoryName[i],arrRightCategoryMark[i],arrWrongCategoryMark[i],temp1);
            }   

            chartBar.dataProvider=arrcolpie;
            chartBar.validateNow();     

 public function addElementInCollection(catgName:String,crt:Number,wrg:Number,i:int):void
        {
            tempobj=new Object();

            tempobj.Label=catgName;
            tempobj.wronganswered=wrg;
            tempobj.rightanswer=crt;

            arrcolpie.addItemAt(tempobj,i);
        }


<mx:ColumnChart id="chartBar" height="100%" width="100%" dataProvider="{arrcolpie}" showDataTips="true"
                        columnWidthRatio="0.4">
