Stacked Column Chart Help Needed

[bdreed35]

My MXML code is pasted below. Every example that I have found of a stacked column chart requires that each metric be returned as a seperate field in your data. What I need is to be able to have my horizontal axis be the month field (this is working), but I need the column subdivided by the site field using the count field. Is this possible within Flex?

    	</mx:Array>
    </mx:ArrayCollection>
