arrayCollection :如何用FLEX填充FLEX

Question

如何在我的mx:AreaSeries中显示arrayCollection的内容？

arrayCollection = [12,31,12,42];
<mx:CartesianChart id="AllChart" dataProvider="{arrayCollection}" width="100%" height="100">
                <mx:AreaSeries" /> <!-- how can I refer to the cells ? Should I use associative array ? -->
</mx:Cartesian Chart>

谢谢

您应该在数组集合中使用对象，如此处的示例：

即：

arrayCollection = [{val:12},{val:31},{val:12},{val:42}];
<mx:CartesianChart id="AllChart" dataProvider="{arrayCollection}" width="100%" height="100">
                <mx:AreaSeries yField="val" /> <!-- how can I refer to the cells ? Should I use associative array ? -->
</mx:Cartesian Chart>
