Question

从数据库中读取数据，在flex中通过线性图表显示，怎么去表示数据源问题

private function queryResult(event:ResultEvent):void{
ff = event.result as ArrayCollection;
}
接收返回来的数组对象 字段包括 血压值和日期
血压 日期
100 2010-01-02
200 2010-01-03
300 2010-01-04
我该如何去添加这个显示呢
Bindable] public var chartDP:Array = [
{day:'Monday2',xueya:ff.getItemAt(0).xueya},
{day:'Tuesday2',xueya:ff.getItemAt(1).xueya},
];

<mx:Canvas label="LineChart" width="100%">
<mx:LineChart dataProvider="{chartDP}" showDataTips="true" width="100%">
<mx:horizontalAxis>
<mx:CategoryAxis
categoryField="day"/>
</mx:horizontalAxis>
<mx:verticalAxis>
<mx:LinearAxis baseAtZero='{false}' autoAdjust="{true}" />
</mx:verticalAxis>
<mx:series>

<mx:LineSeries yField="xueya" displayName="温度"/>
</mx:series>
</mx:LineChart>
</mx:Canvas>
