FLEX：如何使用arrayCollection填充AreaSeries

Question

如何在my mx：AreaSeries中顯示arrayCollection的內容？

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> 

感謝

你應該陣列集合中使用的對象，比如這裏的例子：

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>
