I'm having trouble passing data to an itemRenderer (which is a
BarChart). Essentially what I want to do is have a DataGrid with a few
columns and a chart representing three colors (green, yellow nad red)
as BarSeries components. Normally passing data in to itemRenders works
for me this way:

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml";
layout="absolute">
        <mx:Script>
                <![CDATA[
                        import mx.collections.ArrayCollection;
                        
                        [Bindable] 
                        public var myData:ArrayCollection = new 
ArrayCollection([{colors:
{green:80, yellow:20, red:0}}]);
                        
                ]]>
        </mx:Script>
        <mx:DataGrid dataProvider="{myData}">
                <mx:columns>
                        <mx:DataGridColumn dataField="colors">
                                <mx:itemRenderer>
                                        <mx:Component>
                                                <mx:BarChart 
dataProvider="{data.colors}">
                                                        <mx:series>
                                                                <mx:BarSeries 
xField="green" />         
                                                                <mx:BarSeries 
xField="yellow" />
                                                                <mx:BarSeries 
xField="red" />
                                                        </mx:series>
                                                </mx:BarChart>                  
                        
                                        </mx:Component>
                                </mx:itemRenderer>                              
        
                        </mx:DataGridColumn>
                </mx:columns>
        </mx:DataGrid>  
</mx:Application>
