Read MoreTableau Padawan: Faster Nested Sorts
/
Tableau's sorting behavior is somewhere between "a little weird" and "WTF?!?" for those of used to the nested sorting behavior we can get in Excel and other tools. This is one case where Tableau's "mental model" of sorting doesn't match the mental model of many users, if you'd like Tableau to change this you can vote for the Independent Sorting feature request. Explaining why Tableau sorts the way it does would take a much longer post, for now, I'm going to skip the "why" for the "how" and the "what" and jump into my preferred & faster way to do nested sorting using an ad-hoc calculation.

/
I wanted to take Alteryx out for a drive to see what it could do and decided to look into the Tableau XML, in particular using Alteryx to dynamically update Tableau parameters. This is something I've worked on before (see Creating a Dynamic Parameter with a Tableau Data Blend) and last year at the Tableau Conference Bryan Brandow & Andy Kriebel demoed a solution that they'd built for Facebook with the same basic idea as my Alteryx one.
