Provides access to a group summary object created for a series linked to the DataBinding object.


property SummaryItem: TcxDataSummaryItem read;

Property Value



Since only series provide values to calculate group summaries in Chart Views, a TcxDataSummaryItem group summary object type is automatically created for each series and can be accessed via the SummaryItem property. For data groups and the default categories, the SummaryItem property returns nil.

The SummaryIndex property returns the index of the group summary object in the View’s DataController.Summary.DefaultGroupSummaryItems collection.
