Flex: How to create area chart with only one element in dataProvider?

Question

Hi, When I try to create a Flex Area Chart (I am using Flex SDK 3.4), It does not show any thing if there is only One Element in the dataProvider.

Something like -

<?xml version="1.0"?>
<!-- charts/BasicArea.mxml -->
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"&gt;
  <mx:Script><![CDATA[
     import mx.collections.ArrayCollection;
     [Bindable]
     public var expenses:ArrayCollection = new ArrayCollection([
        {Month:"Jan", Profit:2000, Expenses:1500, Amount:450}
     ]);
     /* ,
        {Month:"Feb", Profit:1000, Expenses:200, Amount:600},
        {Month:"Mar", Profit:1500, Expenses:500, Amount:300} */
  ]]></mx:Script>
  <mx:Panel title="Area Chart">
     <mx:AreaChart id="myChart" dataProvider="{expenses}"
     showDataTips="true">
        <mx:horizontalAxis>
           <mx:CategoryAxis
                dataProvider="{expenses}"
                categoryField="Month"
           />
        </mx:horizontalAxis>
        <mx:series>
           <mx:AreaSeries
                yField="Profit"
                displayName="Profit"
           />
           <mx:AreaSeries
                yField="Expenses"
                displayName="Expenses"
           />
        </mx:series>
     </mx:AreaChart>
     <mx:Legend dataProvider="{myChart}"/>
  </mx:Panel>
</mx:Application>

Where as the charts shows All the elements of dataProvider, if there are 2 or more elements on the dataProvider. Any help/advice on how to get the Area Chart working would be much appreciate.
