    ],
    grandTotalRowIndex: 0,
    grandTotalColumnIndex: 0

}
NOTE
"Measure" refers to a pivot grid field in the data area.

The object mentioned above contains three arrays: rows, columns, and values. Objects in the rows and columns arrays describe header items in the row and column areas and contain the following fields:

  • index - the index of the row/column that contains the header item; used to find a summary value in the values array;
  • value - the field value from the data source that corresponds to the header item;
  • text - the header item's caption;
  • children - an optional array that contains lower-level header items.

The values array contains summary values. Each of them has three indexes. To get a summary value, use the following pattern:

JavaScript
var value = values[/* row index */][/* column index */][/* measure index */];

You can pass grandTotalRowIndex and grandTotalColumnIndex as row index and column index to get grand total values.

NOTE

If you use the XmlaStore and your data area is empty, this method returns the default measure values. They are hidden from the UI until you place the default measure in the data area using the field(id, options) method. The default measure is specified on the OLAP server.

JavaScript
pivotGridDataSource.field(/* measure name */, { area: "data" });
