I gave up getting angry for Lent this year, so I won’t start this blog post ranting about how difficult it is to get my data out of my own FitBit Alta tracking device. Suffice it to say, it is VERY DIFFICULT TO GET MY...
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...
How can you or your organization get more out of your raw data? How do you make the data understandable to the masses? And how do you make better decisions based on the data? This show, Ben, Derrick, and Alex have a roundtable discussion about making...
Are you considering taking a Tableau training course? If so, then I need 15 minutes of your time. Hi, I’m a Tableau trainer. I’ve taught students from all over the world, both in person and virtually. I spend most of my day working with Tableau...
Spring is here in D.C. For most people, that means any number of things – from the Cherry Blossom Festival, the Rock n’ Roll Marathon, patio dining or, for those as unlucky as I, horrendous seasonal allergies. But, there’s one recurring tradition from D.C. government that...
Time for another question from Tableau Training, this time a question asked by Daniel from a DII: Intermediate course in Kuala Lumpur, Malaysia: "I want to show my actual sales on a line graph, but I also want to combine that to show budgeted sales after...
In our final article in the Deep Dive on Dates, we’ll explore how to take a start date for different products and normalize it to a wee- by-week comparison from week one forward. This article was inspired by one of my Desktop I: Fundamentals students from...
We take a moment - actually, a whole show - to remember Hans Rosling, who passed away on Feb. 7, 2017. Ben and Dan talk about their most memorable moments with Hans and attempt to imagine where the world of data is headed, as Hans...
Electric vehicles have been selling in significant numbers for several years. Tesla has made a splash in the ultra-luxury market with the Model S, and they took deposits from excited buyers amounting to over $15 billion of backlog for the mass market Model 3 sedan. GM,...
As far back as I can remember, the Chicago Cubs were, to me, family. From my grandfather and father growing up spending summer days taking the L down to Addison, grabbing a bleacher seat and hand-scoring the game. They got to watch the greats play...
For this article in our Deep Dive on Dates, we’re going to build a filter in the form of a calendar. Our user can select an entire month or a series of days to create a subset of data on the dashboard. Here’s a preview...

Let’s continue our exploration of dates in our Deep Dive. In Part 6, we’re going to focus on how we can create rolling dates. A rolling date is taking a specific date, such as order date, and then adding a certain amount of days, months or...
Let’s continue on with our Deep Dive into Dates. This article, we’ll explore custom dates. The name admittedly is a bit of a misnomer and only really make sense if you understand date parts and date values. Make sure to catch up on this series...
We’re continuing our Deep Dive into Dates with an examination of the Exact Date value. Remember to catch up on the previous three articles where I introduced dates (discrete vs. continuous) and some key date functions. Let’s get started! Exactly What is Exact Date? In our first...
We’re continuing our Deep Dive into Dates with further exploration into date specific functions. In this article, we’ll cover DATEADD, DATEDIFF and DATETRUNC. My goal is not only to show you how to use them but to give you some real world examples of when they’d be...
