  ,[ partition_field, ... ]

Arguments

measure

An aggregated measure that you want to see the running sum for.

sort order field

One or more measures and dimensions that you want to sort the data by, separated by commas. You can specify either ascending (ASC) or descending (DESC) sort order.

Each field in the list is enclosed in {} (curly braces), if it is more than one word. The entire list is enclosed in [ ] (square brackets).

partition field

(Optional) One or more dimensions that you want to partition by, separated by commas.

Each field in the list is enclosed in {} (curly braces), if it is more than one word. The entire list is enclosed in [ ] (square brackets).

Example

The following example calculates a running sum of sum(Sales), sorted by Sales, partitioned by City and State.

runningSum
(
  sum(Sales), 
  [Sales ASC], 
  [City, State]
)

The following example calculates a running sum of Billed Amount, sorted by month ([truncDate("MM",Date) ASC]). The fields in the table calculation are in the field wells of the visual.

runningSum
(
  sum({Billed Amount}),
  [truncDate("MM",Date) ASC]
)

The following screenshot shows the results of the example. The red labels show how each amount is added ( a + b = c ) to the next amount, resulting in a new total.
