Any reason you're going through the trouble of converting to an
ArrayCollection? The following will work with your XML data just fine...
<mx:ColumnChart id="mybarchart" dataProvider="{billData.bill}"
showDataTips="true" paddingLeft="5" paddingRight="5" width="100%"
height="100%">
<mx:horizontalAxis>
<mx:CategoryAxis categoryField="@account"/>
</mx:horizontalAxis>
<mx:series>
<mx:ColumnSeries displayName="Electric Bill" xField="@account"
yField="electricitybillamount" />
<mx:ColumnSeries displayName="Gas Bill" xField="@account"
yField="gasbillamount" />
<mx:ColumnSeries displayName="Water Bill" xField="@account"
yField="waterbillamount" />
</mx:series>
</mx:ColumnChart>

Hey everyone I am having issues with using an arraycollection as a
dataprovider. I start with an xml variable (see below) then I convert
it to an ArrayCollection using ArrayUtil.toArray and I use the result
as a dataprovider. If I trace the dataprovider it prints out the xml
data, but my chart is empty. Can you use ArrayUtil on xml data with
this many nodes? I have spent way to much time on this.
Here is what I have starting with my XML file.
