RUNNING_SUM(SUM([Profit])) computes the running sum of SUM(Profit). In the calculation editor that opens, do the following: This formula calculates the running sum of profit sales. If the start
Open Tableau and connect to the Sample-Superstore saved data source. Population covariance is the appropriate choice when there is data available for all items of interest as opposed to when there is only a random subset of items, in which case sample covariance (with the WINDOW_COVAR function) is appropriate. For example, in the following table, the calculation is computed across columns (YEAR(Order Date)) for every row (MONTH(Order Date)). The expression is passed directly to a running analytics extension service instance. Table calculations are a special type of calculated field
For example, in the following table, the calculation is computed across columns (YEAR(Order Date)), down a row (MONTH(Order Date)), and then across columns again for the entire table. For more information about these options, see The basics: addressing and partitioning section. Use FIRST()+n and LAST()-n for
