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... No Comments.
I recently had the privilege of presenting a preview of Tableau’s Project Maestro 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 in Maestro to capture the […]Continue Reading... No Comments.
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... 2 Comments.
I love hex maps! Especially for the United States, you can keep states in a basic geographic orientation, but eliminate the visual perception problems caused by the fact that some states are huge compared to others (and Alaska and Hawaii shift the scale when added). But there are a few headaches that can occur when […]Continue Reading... 7 Comments.
Tableau’s new data prep tool, Maestro, is now in public beta, and I’m loving it! While the first beta doesn’t necessarily include all the features that might soon make it to a production release, what blows me away is the overall paradigm. It brings the intuitiveness and transparency that Tableau brought to visual analytics and […]Continue Reading... 2 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 competed in the Tableau Iron Viz where Tristian Guillevin, Jacob Olsufka and I raced to build a dashboard in 20 minutes! One of the most incredible things about Tableau is how versatile it is as a tool. You can spend hours to build a stunning Tableau dashboard or just a few minutes to […]Continue Reading... 9 Comments.
Ah, games and Tableau – two of my favorite things together! And it isn’t all just about fun and games, it’s about learning and pushing the limits to see what Tableau can do and how to best use the features and capabilities of Tableau to turn an idea into something that works! I’ll have a few blog posts […]Continue Reading... 4 Comments.
I was part of a conversation recently where something like this was said: “We need a data model that will bring all of our data together so that we can analyze risk and do predictive analytics… No, just build the model, don’t worry about using Tableau – we’ll do that after you build the model […]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.
