AggMax
AggMax returns an aggregator that computes the maximum value, within an aggregation group, for each input column.
Syntax
Parameters
| Parameter | Type | Description |
|---|---|---|
| pairs | String... | The source column(s) for the calculations.
|
Caution
If an aggregation does not rename the resulting column, the aggregation column will appear in the output table, not the input column. If multiple aggregations on the same column do not rename the resulting columns, an error will result, because the aggregations are trying to create multiple columns with the same name. For example, in table.aggBy([agg.AggSum(“X”), agg.AggAvg(“X”)]), both the sum and the average aggregators produce column X, which results in an error.
Returns
An aggregator that computes the maximum value, within an aggregation group, for each input column.
Examples
In this example, AggMax returns the maximum Y value as grouped by X.
In this example, AggMax returns the maximum Y value (renamed to Z), as grouped by X.
In this example, AggMax returns the maximum Y string and maximum Number integer as grouped by X.
In this example, AggMax returns the maximum Number integer, as grouped by X and Y.
In this example, AggMax returns the maximum Number integer, and AggLast returns the last Number integer, as grouped by X.
