My first time to New York City, I noticed something on just about every restaurant I walked by. There was one of these signs displayed at the front window showing off the inspection grade. Obviously, I avoided every one of the C restaurants I came...
It’s no secret that I’m a math nerd. Or that I’m raising a math nerd. For his birthday, my son Judah got a Curiosity Box that contained a cool looking t-shirt. I spent some time explaining what was going on in this magical circle, but...

Outside of being a powerful data visualization tool, Tableau is known for its ability to connect to just about anything. This includes a multitude of brand-name databases. But there’s a rising database on the block that’s making waves in the industry called EXASOL. What Is EXASOL? EXASOL...
I recently wrote an article encouraging every Tableau user of every level of proficiency to take the Desktop I: Fundamentals course. Now I’m going to do the same for the next level of training, Desktop II: Intermediate. Here’s what I’ve seen from traveling literally around...
Quite frequently, students in training will ask “How do I make a gauge in Tableau?” While it's possible, it's not one of the default chart types in Tableau and can be somewhat time consuming. Instead, I recommend using bullet graphs, but why? What is it about...
If you’ve kept up with import.io, you know that there were recently some changes to their service model. Unfortunately, free accounts no longer offer API integration, which means we must deprecate the Magic API. The good news is that despite the changes, we have rewritten...
Here’s a question that came out of a class from one of our other trainers: “Student wants a running sum to restart every time the value drops to zero.” How very interesting – a table calculation with a conditional scope. Let’s tackle this problem. Scope & Direction First, let’s...
The latest question from Tableau Training comes from Ryan, who was in a DII: Intermediate course in New York City. "I know I can show top n products with a parameter, but how can I get the top n products nested within other fields?" This is a great...
One of my favorite announcements at TC16 was the new ability for Tableau to natively read shapefiles. Shapefile (.SHP) is a data type used for storing maps. This feature totally revolutionizes the things we can accomplish with our maps inside of Tableau. For more information on using shapefiles...
Ah, the month-on-month comparison. I’m not going to bore you with a sermon on the ins and outs of monthly comparisons, but I do want to explain what this particular variation accomplishes. In my previous post on comparing an incomplete week to the same days of...
Tableau just announced the beta release of Tableau 10.3, and it’s clear that they have been listening to the worldwide Tableau community with the new features and enhancements. While a lot of the new stuff focuses on Tableau Server and Tableau Online, there are exciting...

For the past few months, I’ve been working with a client for whom tracking performance is a matter of life and death. Okay, maybe it’s not that dramatic … but they care a lot about player engagement and revenue streams for the video games they...
Over the course of the past year, I’ve combined my love of genealogy with an increasing interest in data visualization. I’ve long had an Ancestry.com account, but I always wanted a more visual representation of where I came from. Cue Tableau. After working in short...
This week, I gave a talk on level of detail expressions at the Atlanta Tableau User Group. Preparing for that talk, I watched lots of video. The speech by Ian Coe and Adam Kamor, Pick Your Poison, LOD Expression or Table Calc, inspired this dashboard....
Well it’s that time of year again – the college basketball season comes to a close with the madness that is the NCAA tournament. Conference tournaments gave us a bit of a warmup, but now it’s time for the real deal. Brackets will bust, Cinderella’s...
Evictions are a sensitive subject in San Francisco. Long-term residents are being pushed out of their homes due to rising rent – some through evictions. Two of the most common, and controversial, ways to evict someone are the Ellis Act and Owner Move-in. The Ellis Act...
