Data blending and joining are incredible Tableau features! Here you’ll find tips and tricks for data blending and joining or see dashboards and dataviz that makes use of data blending or joining.
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 needed to unpivot some data and realized, the Tableau devs are truly miracle workers! Unpivot Data – […]Continue Reading... No Comments.
Cross database joins have been available in Tableau for a while now – and I love the ability to join data at a row-level across various databases and files! And union functionality is available, but for now, only if you are dealing with tables in the same database (or files or Excel tabs). But what […]Continue Reading... 3 Comments.
I recently had the privilege of presenting a preview of Tableau’s Project Maestro (now known as Tableau Prep) to the Amazon Tableau User Group. This is not the exact presentation, but is a very similar data flow to the one I demonstrated there. The flow also shows how to replicate a Level of Detail calculation […]Continue Reading...

Often, you’ll have data that looks something like this: Every day, there are new records for projects that give the latest status and count of hours used. Often a project spans multiple days and the status can change and count of hours might go up. But if I want to get the most recent […]Continue Reading... 3 Comments.
I used to think you couldn’t hot-swap geographic levels of detail in a Tableau visualization. And, before Tableau 10, you couldn’t. I mean, of course in Desktop or web authoring mode you can drag and drop fields, but for the end-user of a dashboard that wasn’t an option. You might have thought to use […]Continue Reading...

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.
The Tableau technique shown here is to use an action to update an entire dashboard, including the filter selection and the view which triggered the action. The trick doesn’t have to be used to navigate hierarchies or hierarchical data, but it happens to work very nicely for that purpose. Let’s say you have a Tableau […]Continue Reading... No Comments.
Tableau 10.2 is almost here! And it’s time to celebrate! One thing I’ve always wanted to do in Tableau is create interactive historical maps that changed based on the selected time-frame. We are fairly familiar with the shape of things now – countries, states, counties – but how did things look in the past? What […]Continue Reading...

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.
So, I previously wrote about how to use data blending to get data from multiple Google Analytics data sources into a single Tableau view. But that’s somewhat tedious and so 2013. There’s now a much better way! Using Google Sheets to track Google Analytics It kind of makes sense that Google Sheets can talk to […]Continue Reading... 12 Comments.
