Using aggregation functions in chart expressions

Using aggregation functions in chart expressions

The argument expression of one aggregation function must not contain another aggregation function.

The expression must not contain aggregation functions, unless these inner aggregations contain the TOTAL qualifier. For more advanced nested aggregations, use the advanced aggregation function Aggr, in combination with calculated dimensions.

An aggregation function aggregates over the set of possible records defined by the selection. However, an alternative set of records can be defined by using a set expression in set analysis.
