Summary calculations are aggregate functions used for sub-totals and totals. Summary calculations can be set in the Domain Designer or in the Ad Hoc view.
...
In general, you can change the summary calculation of any measure. By default, Zoola™ summarizes fields of each datatype as follows:
Datatype | Default Summary | Description |
|---|---|---|
Numeric | Sum | Displays the sum of all values in the set. |
Date | CountAll | Displays the total number of values in the set. |
String | CountAll | Displays the number of values in the set. |
Boolean | CountAll | Displays the number of values in the set. |
Aggregate | AggregateFormula | For a calculated field that uses an aggregate function, uses the same aggregate formula as the summary. |
Combined | None | For a calculated field that combines an aggregate function with a non-aggregate function, the summary calculation is null. |
Select from the following options to set a measure's summary function in any type of view:
