EXPANDALL

In a visual calculation, an expression evaluated at the bottom level of an axis.

A visual calculation works on the table behind a visual: a row for each group on the visual's axes and one for each of their totals. To try one in the OAX view, give a table that shape with DEFINE TABLE ... WITH VISUAL SHAPE: its axes, their groups, the TRUE/FALSE column that marks each group's totals and the order, and with DENSIFY a name for the column that marks rows the shape fills in. Then write the calculation as a COLUMN of that table, as Power BI's own queries do. The examples below are queries of that kind, small enough to check by hand.

Group: Window and visual calculations. Compatible with DAX.

Syntax

EXPANDALL ( <expression>, <axis> )
EXPANDALL ( <axis> )

Returns

Same type as the expression. The expression's value over the lowest-level rows under the current row.

Remarks

• On the grand total, EXPANDALL ( AVERAGE ( [Liters] ), ROWS ) averages every quarter, where EXPAND would average the years.
• A field alone over several rows is an error: aggregate it.
• It works only in a visual calculation; in a measure, a calculated column or a plain query it is an error.

Examples

Average of the bottom level against average of the children

On the grand total the two differ: four quarters average 125, two years 250.
