Aggregate functions - Amazon QuickSight

Aggregate functions

Aggregate functions are only available during analysis and visualization. Each of these functions returns values grouped by the chosen dimension or dimensions. For each aggregation, there is also a conditional aggregation. These perform the same type of aggregation, based on a condition.

When a calculated field formula contains an aggregation, it becomes a custom aggregation. To make sure that your data is accurately displayed, Amazon QuickSight applies the following rules:

  • Custom aggregations can't contain nested aggregate functions. For example, this formula doesn't work: sum(avg(x)/avg(y)). However, nesting nonaggregated functions inside or outside aggregate functions does work. For example, ceil(avg(x)) works. So does avg(ceil(x)).

  • Custom aggregations can't contain both aggregated and nonaggregated fields, in any combination. For example, this formula doesn't work: Sum(sales)+quantity.

  • Filter groups can't contain both aggregated and nonaggregated fields.

  • Custom aggregations can't be converted to a dimension. They also can't be dropped into the field well as a dimension.

  • In a pivot table, custom aggregations can't be added to table calculations.

  • Scatter plots with custom aggregations need at least one dimension under Group/Color in the field wells.
