Calculations in Tableau are Powerful! These posts either deal extensively with calculations or demonstrate techniques that use calculations.
One of the questions that comes up quite often is “How do I remove duplicate records in Tableau Prep?” or “How do I dedup data in Tableau Prep?” Some data preparation tools have a specific feature to do this.

Tableau 2018.1 introduces a lot of new features, especially geospatial features that open a whole new world of data exploration and analysis. With support for SQL Server geospatial data types, there are near-infinite possibilities. I’m sure I’ll have more than a few posts on various options soon!

You know you have a great piece of software when you can use its paradigm to come up with workarounds to features that don’t yet exist. Such is the case with Tableau Prep (formerly Project Maestro).

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.
Happy New Year! Even as 2016 was winding down, I found myself with a challenge dealing with time. And I thought I’d share some of my thoughts about a possible approach. Here’s the challenge: You have a database with transactional data, that is data where the rows are inserted, updated and deleted based on events. […]Continue Reading... No Comments.
I really love the Tableau Community Forums. If you haven’t ever experienced the forums, you really should! It’s a vibrant community all centered around helping people learn Tableau and solve real world problems!
