Use the dataField property to specify the data field used to generate the summary,
the label property to specify the name of the data field created to hold the summary data,
and the operation property to specify how to create the summary for numeric fields.
You can specify one of the following values:
SUM, MIN, MAX, AVG, or COUNT.
The following example creates summary rows based on two fields of the data provider of the AdvancedDataGrid control:
<mx:AdvancedDataGrid id="myADG"
initialize="gc.refresh();">
<mx:dataProvider>
<mx:GroupingCollection id="gc" source="{dpFlat}">
<mx:Grouping>
<mx:GroupingField name="Region">
<mx:summaries>
<mx:SummaryRow summaryPlacement="group">
<mx:fields>
<mx:SummaryField dataField="Actual"
label="Min Actual" operation="MIN"/>
<mx:SummaryField dataField="Actual"
label="Max Actual" operation="MAX"/>
</mx:fields>
</mx:SummaryRow>
</mx:summaries>
</mx:GroupingField>
<mx:GroupingField name="Territory">
<mx:summaries>
<mx:SummaryRow summaryPlacement="group">
<mx:fields>
<mx:SummaryField dataField="Actual"
label="Min Actual" operation="MIN"/>
<mx:SummaryField dataField="Actual"
label="Max Actual" operation="MAX"/>
</mx:fields>
</mx:SummaryRow>
</mx:summaries>
