Question

此flashbuilder 4.6应用程序根据下拉列表中的所选名称在折线图上显示单个lineSeries，并且lineseries数据显示正常。但是，工具提示显示[object Playername_returntype]而不是下拉列表选择名称。

我还想从下拉列表中动态地将相同的所选名称分配给lineseries的displayName，但是无法实现此目的。结果显示[工具提示中的[object Playername_returntype]。

非常感谢任何帮助。

感谢。

不完全确定你的目标，但对于LineSeries displayName，这就是我所做的：

为每个Line Series创建一个[Bindable] String变量，然后每当数据发生变化时，只需为变量赋值即可。在您的示例中：

private function comboBoxChange():void
    {
        var selectedName:String = dropDownList.selectedItem.lname;
        getpool_ratings_yr1Result.token = pool_ratings_yr1Service.getpool_ratings_yr1(selectedName);
        // Private Bindable String variable(myString) assigned earlier
        myString = selectedName;

    }

然后在你的mxml：

displayName="{myString}"

希望足够清楚！
