OFFSET – value from previous, next… row in visual (DAX – Power Pivot, Power BI)
OFFSET is a function, that in Power BI shows the value from another row (previsou, next etc.)
Like here, it shows the previous value:
OFFSET is used in a CALCULATE function, it can have two or three arguments:
- Previous sumo of Price = CALCULATE(
SUM(Sheet1[Price]),
OFFSET(
-1,
ALLSELECTED(Sheet1[Color])))
Because:
- -1 defines the “movement”. For example -1 means previous row, +2 means two rows after etc.
- ALLSELECTED is used for column we are working with
- The last, voluntary, argument can contain the ORDERBY function. It defines the direction used for counting (ASC or DESC)
