[flexcoders] Linecharts and dataproviders

[flexaustin]

Its been way to long since I have used Flex Charting. I have this XML data, 
which I need to display in a lineChart, but I seem to be having issues with 
getting it output 5 lines (one for each device#) based on the data.  I end up 
with one line? 

TIA, J

Here is my linechart:
 
 <mx:LineChart id="lineChart"
            showDataTips="true"
            dataProvider="{_myXML.read.device}"
            width="100%"
            height="100%"
          >

Here is my series:

<mx:series>
            <mx:LineSeries yField="@usage"
                    form="curve"
                    displayName="Usage" />
           
        </mx:series>


Here is my data:
