Calculations in Tableau are Powerful! These posts either deal extensively with calculations or demonstrate techniques that use calculations.
I recently came across this post by Simona Loffredo in which she describes a certain type of data structure, why it wasn’t ideal for analysis, and how to reshape it using Alteryx. While I love Alteryx and really love how it can be used alongside Tableau, I get especially excited when I can do something without […]Continue Reading... 1 Comment.
