Washington, D.C. is one of the most beautiful and historically rich cities in America. As someone who has lived in the area for over a decade, I can vouch for one park that never disappoints – the promenade between the Capitol and the Potomac known...
George Santayana once said that “those who cannot remember the past are condemned to repeat it.” Every history professor I had from high school through college repeated some variation of that phrase. At one point, I hated history. I could not force myself to memorize...
Campers have a lot of options today! It’s not just a trip to the woods anymore but a plethora of special activities and camps to choose from. I can imagine the arduous process of finding something kids like that’s also close to your home. In Washington,...
After seeing my colleague, Maureen, dive into NYC Open Data with posts on NYC Vehicle Crashes and Parking Tickets, I figured I should take a look around myself to see what other kinds of data the city has made public. Turns out there are more than 1300...
Data stories are about people. We make charts about customers buying things, students earning grades, investors placing trades and on it goes. The people reading and making charts also have stories to tell, but their experiences are hard to describe with numbers and simple shapes....

While not a regular occurrence, I have come across situations where a client wants to display a hidden sheet with an action filter but wants to enable different worksheets to activate the hidden sheet. If the sheets are filtering on different fields when you set an...
This is the third article in our Tableau Deep Dive on level of detail. Part 1 reviewed the idea of detail. Part 2 introduced level of detail calculations and examined the Include LOD calculation. Let’s now jump into Exclude. A Use Case For our examples in this article, we’ll...
One of the common problems that clients are seeking to solve is a way to easily compare values from two different periods against each other. They want the ability to compare the same period between two years, a period against an immediately preceding period and...
In the previous article of this Deep Dive on LODs, we talked about Detail in general for Tableau Desktop. In Part 2, we’ll explore the Include level of detail calculation. Start With the Data Before I go into Tableau Desktop, I always think it’s foundationally important to...
I’ve been a storm chaser since I was eight years old. My grandfather volunteered for the Perkins Civil Defense, and part of his duty was to sit on a hilltop anytime severe weather came into the area. He let me tag along, and I’ve been...
Level of detail (LOD) is a feature that was introduced in Tableau Desktop v9. While it offers a great amount of flexibility and control over how you use the data in your visualization, it can be a bit tricky to fully understand. We teach level of...
