    <p>I've studied your problem, deeping in initializing ColumnChart component. There is a feature, that all columns from series is placed in separate layer. So, either green columns are on the top or red. No posibility to change parent of one column from series...I'm afraid you have to override the basic behavior of component and place all columns in the same container and sort their depths. I drew an example:</p> <pre><code>&lt;s:Application xmlns:fx="http://ns.adobe.com/mxml/2009" xmlns:s="library://ns.adobe.com/flex/spark" xmlns:mx="library://ns.adobe.com/flex/mx" width="900" height="600"&gt; &lt;fx:Script&gt; &lt;![CDATA[ import mx.charts.series.items.ColumnSeriesItem; import mx.collections.ArrayCollection; [Bindable] public var expenses:ArrayCollection = new ArrayCollection([ {Month:"Jan", Profit:200, Expenses:100, Expenses2:50}, {Month:"Feb", Profit:1000, Expenses:2000, Expenses2:500}, {Month:"Mar", Profit:1100, Expenses:500, Expenses2:100}, {Month:"Apr", Profit:1300, Expenses:900, Expenses2:1000}, {Month:"May", Profit:900, Expenses:1200, Expenses2:1000}, {Month:"June", Profit:1000, Expenses:2000, Expenses2:1500} ]); private var items:Array = []; private function init():void { items = []; for (var i:int=0; i&lt;myChart.series.length; i++) { var series:ColumnSeries = myChart.series[i] as ColumnSeries; for (var j:int=0; j&lt;series.items.length; j++) { if (!items[j]) items[j] = []; var item:ColumnSeriesItem = series.items[j] as ColumnSeriesItem; items[j][i] = item; series.parent.addChild(item.itemRenderer as DisplayObject); } } sort(); } private function sort():void { var h:Number = myChart.height - 50; for (var i:int=0; i&lt;items.length; i++) { var group:Array = items[i]; group.sort(sortFunction); for (var j:int=0; j&lt;group.length; j++) { var item:ColumnSeriesItem = group[j] as ColumnSeriesItem; item.itemRenderer.parent.setChildIndex(item.itemRenderer as DisplayObject, group.length - j - 1); item.min = NaN; if (j &gt; 0) item.min = h - group[j-1].itemRenderer.height; } } } private function sortFunction(item1:ColumnSeriesItem, item2:ColumnSeriesItem):int { var yValue1:int = item1.item[Object(item1.element).yField]; var yValue2:int = item2.item[Object(item2.element).yField]; return (yValue1 &lt; yValue2) ? -1 : (yValue1 &gt; yValue2) ? 1 : 0; } ]]&gt; &lt;/fx:Script&gt; &lt;fx:Declarations&gt; &lt;!-- Place non-visual elements (e.g., services, value objects) here --&gt; &lt;/fx:Declarations&gt; &lt;s:BorderContainer width="100%" height="100%" &gt; &lt;s:layout&gt; &lt;s:VerticalLayout horizontalAlign="center"/&gt; &lt;/s:layout&gt; &lt;mx:ColumnChart id="myChart" width="65%" dataProvider="{expenses}" showDataTips="true" type="overlaid" updateComplete="init()" &gt; &lt;mx:horizontalAxis&gt; &lt;mx:CategoryAxis dataProvider="{expenses}" categoryField="Month" /&gt; &lt;/mx:horizontalAxis&gt; &lt;mx:series&gt; &lt;mx:ColumnSeries yField="Profit" displayName="Profit" &gt; &lt;mx:fill&gt; &lt;s:SolidColor color="0x00ff00"/&gt; &lt;/mx:fill&gt; &lt;/mx:ColumnSeries&gt; &lt;mx:ColumnSeries yField="Expenses" displayName="Expenses" &gt; &lt;mx:fill&gt; &lt;s:SolidColor color="0xff0000"/&gt; &lt;/mx:fill&gt; &lt;/mx:ColumnSeries&gt; &lt;mx:ColumnSeries yField="Expenses2" displayName="Expenses2" &gt; &lt;mx:fill&gt; &lt;s:SolidColor color="0xffff00"/&gt; &lt;/mx:fill&gt; &lt;/mx:ColumnSeries&gt; &lt;/mx:series&gt; &lt;/mx:ColumnChart&gt; &lt;mx:Legend dataProvider="{myChart}"/&gt; &lt;mx:DataGrid dataProvider="{expenses}" editable="true"&gt; &lt;mx:columns&gt; &lt;mx:DataGridColumn dataField="Month" editable="true"/&gt; &lt;mx:DataGridColumn dataField="Profit" editable="true"/&gt; &lt;mx:DataGridColumn dataField="Expenses" editable="true"/&gt; &lt;mx:DataGridColumn dataField="Expenses2" editable="true"/&gt; &lt;/mx:columns&gt; &lt;/mx:DataGrid&gt; &lt;/s:BorderContainer&gt; &lt;/s:Application&gt; </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
