    "description": "The SummaryField2 class represents a single property in a SummaryRow instance. Each SummaryRow instance specifies one or more SummayField2 instances that are used to create a data summary.  <p><b>Note: </b>In the previous release of Flex, you used the SummaryField class to create summary data. The SummaryField2 class is new for Flex 4 and provides better performance than SummaryField.</p>  <p>Use the <code>dataField</code> property to specify the data field used to generate the summary, the <code>label</code> property to specify the name of the data field created to hold the summary data, and the <code>summaryOperation</code> property to specify how to create the summary for numeric fields. You can specify one of the following values: <code>SUM</code>, <code>MIN</code>, <code>MAX</code>, <code>AVG</code>, or <code>COUNT</code>.</p> Or you can specify an ISummaryCalculator implementation to calculate the summaries.  <p>The following example creates summary rows based on two fields of the data provider of the AdvancedDataGrid control:</p>  <pre>\\n &lt;mx:AdvancedDataGrid id=&quot;myADG&quot;\\n initialize=&quot;gc.refresh();&quot;&gt;\\n &lt;mx:dataProvider&gt;\\n &lt;mx:GroupingCollection id=&quot;gc&quot; source=&quot;{dpFlat}&quot;&gt;\\n &lt;mx:Grouping&gt;\\n &lt;mx:GroupingField name=&quot;Region&quot;&gt;\\n &lt;mx:summaries&gt;\\n &lt;mx:SummaryRow summaryPlacement=&quot;group&quot;&gt;\\n &lt;mx:fields&gt;\\n &lt;mx:SummaryField2 dataField=&quot;Actual&quot;\\n label=&quot;Min Actual&quot; summaryOperation=&quot;MIN&quot;/&gt;\\n &lt;mx:SummaryField2 dataField=&quot;Actual&quot;\\n label=&quot;Max Actual&quot; summaryOperation=&quot;MAX&quot;/&gt;\\n &lt;/mx:fields&gt;\\n &lt;/mx:SummaryRow&gt;\\n &lt;/mx:summaries&gt;\\n &lt;/mx:GroupingField&gt;\\n &lt;mx:GroupingField name=&quot;Territory&quot;&gt;\\n &lt;mx:summaries&gt;\\n &lt;mx:SummaryRow summaryPlacement=&quot;group&quot;&gt;\\n &lt;mx:fields&gt;\\n &lt;mx:SummaryField2 dataField=&quot;Actual&quot;\\n label=&quot;Min Actual&quot; summaryOperation=&quot;MIN&quot;/&gt;\\n &lt;mx:SummaryField2 dataField=&quot;Actual&quot;\\n label=&quot;Max Actual&quot; summaryOperation=&quot;MAX&quot;/&gt;\\n &lt;/mx:fields&gt;\\n &lt;/mx:SummaryRow&gt;\\n &lt;/mx:summaries&gt;\\n &lt;/mx:GroupingField&gt;\\n &lt;/mx:Grouping&gt;\\n &lt;/mx:GroupingCollection&gt;\\n &lt;/mx:dataProvider&gt;\\n \\n &lt;mx:columns&gt;\\n &lt;mx:AdvancedDataGridColumn dataField=&quot;Region&quot;/&gt;\\n &lt;mx:AdvancedDataGridColumn dataField=&quot;Territory_Rep&quot;\\n headerText=&quot;Territory Rep&quot;/&gt;\\n &lt;mx:AdvancedDataGridColumn dataField=&quot;Actual&quot;/&gt;\\n &lt;mx:AdvancedDataGridColumn dataField=&quot;Estimate&quot;/&gt;\\n &lt;mx:AdvancedDataGridColumn dataField=&quot;Min Actual&quot;/&gt;\\n &lt;mx:AdvancedDataGridColumn dataField=&quot;Max Actual&quot;/&gt;\\n &lt;/mx:columns&gt;\\n &lt;/mx:AdvancedDataGrid&gt;\\n </pre>   The <code>&lt;mx.SummaryField2&gt;</code> inherits all the tag attributes of its superclass, and defines the following tag attributes:</p>  <pre>\\n &lt;mx:SummaryField2\\n <b>Properties </b>\\n dataField=&quot;<i>No default</i>&quot;\\n label=&quot;<i>No default</i>&quot;\\n summaryOperation=&quot;<i>SUM</i>&quot;\\n /&gt;\\n </pre>",
