In today's question we will be answering how we can keep the returned results limited to a defined/definable number of rows. That means for example if we say we want only 200 rows to be returned but we have four different segments then each segment should only hold 50 results. If we increase to 300... Continue Reading →
Diagonal running sums in a table – 2nd edition (and why it is actually window sums)
Misunderstandings happen all over the place and Tableau and it's Forums are no exception to that rule. Specifically when referring to my last blog entry on the above matter, the provided data was so simplified that my resulting understanding turned out to be wrong. What the user wanted was not - as I had deduced... Continue Reading →
Diagonal running sums in a table
Hi there. In today's episode of "everything table calc" we will be having a look at how to compute a diagonal running_sum in a table in Tableau.

Also, there can be multiple instances of null values in succession. For this exercise, however, we will be going through three levels of difficulty to gradually evolve our understanding.

Comparing table calculations in a tooltip
A while ago a user wanted to be able to show in a tooltip the deviations of the running sums of his actuals vs the running sums of several different budgets, depending on which budget the user would hover over
Comparing independent table calculation results from different sheets
Just as I had finished my blog on how to transfer results of a table calculation from one sheet to another, a new but related question popped up on the forums. This time, the user wanted to compare two independent rankings. I.e. he did not want to compare on a product level but instead he wanted to compare Rank#1 from Ranking A to Rank#1 from Ranking B etc where both rankings could be based on completely independent filters.
