Totals
The Grid dashboard item enables you to add a summary value (a total) calculated against displayed values of an individual column, and to show the result under this column. Note that you can add any number of totals for each column. For example, you can obtain the number of column records, average or maximum value, etc.
Totals Overview
You can use the following summary functions when creating totals.
Count - The number of records.
Sum - The sum of the values.
Min - The smallest value.
Max - The largest value.
Average - The average of the values.
Auto - The total is calculated using the type of summary function specified for the measure corresponding to the current Grid column. Note that in this case, the total is calculated based on values of the corresponding data field from the underlying data source.
Note
Note that the Auto type is not supported when the Grid is bound to the OLAP data source.
You can create totals using different sets of summary functions. This depends on the type of the data source field providing data for the target column.
Important
Note that the Auto type is available only for the measure column.
