I met Michael at the first or second Tableau Conference. It was particularly memorable meeting him because he is scary smart and his appearance is remarkably similar to Art Garfunkle. Michael specializes in creating impressive social network graphs, performing target customer analysis and integrating market...
I was excited when Tableau announced the upcoming web connector at last year’s conference. I had envisioned it getting data from web pages into Tableau as easily as when I use import.io. Just enter a URL, automatically parse the structure and return the data. It...
Somehow, I didn’t actually meet Anya in person until the conference in Washington, D.C., a few years ago. I knew of her and her work with Tableau well before then. Her personality in her blog posts is consistent with her personality in person. She is...
We’ll continue on with the next item in the Filtering category: "Replace quick filters showing 'Only Relevant Values' and high count of quick filters with dashboard filter actions. They will cascade as your user interacts, and they perform faster." Cascading filters? Sounds exciting! I Got 99 Problems … As we...
My new favorite trick in Tableau is replacing a section of a dashboard with new content in a way that leaves everything clickable and doesn’t require navigating to a different tab. The basics of this idea were covered in the “Sheet Swapping and Popping” post...
One of the biggest thrills of my career was becoming a Tableau Zen Master last year. I’m an old guy, so that’s saying a lot. Since nominations are being accepted for the 2015-2016 Zen Masters, I thought I would provide a few thoughts on the...
The next guideline in our list of Filtering tips is: "Keep range quick filters simple. The more complex the range, the slower the query." Sound exciting? Let’s go! Quick Filter Overview Quick filters are a quick and easy way to add interactivity to your visualization or your dashboard, either...
It’s “Action Month” at Tableau Public. Actions are one of my favorite Tableau features. They allow you to easily create interactive dashboards, and the community has used them in some very creative ways. Actions are the perfect example of what Tableau does best. They’re simple...
The next item in our Filtering checklist is: "Avoid quick filters or actions that drive context filters. These require reloading the context table and should be avoided wherever possible." There’s a lot to digest there, so let’s get started. What Is a Context Filter? The filters that you add...
A powerful feature within Alteryx is the Download tool under the Connectors tab. It’s useful for pulling information down from the web. As the amount of data available on the web grows, the value of being able to pull information into a workable format in...
When creating a data visualizations using U.S. weather data, I’m running into a problem. I have weather data in a dense grid from NOAA, but no way to filter individual states. Some data sources show the contiguous U.S. while others are sections of satellite coverage....
The next item in our Filtering checklist is: "Avoid high-cardinality quick filters (multi-select or drop-down lists). High-cardinality quick filters are slow to load and render." Let’s jump right in and see how high cardinality in your quick filters can negatively impact performance. What is Cardinality? In SQL, the cardinality...
The recent floods in Texas and Oklahoma hit home for me. I live outside of Dallas and InterWorks has three offices in Oklahoma. We’ve seen double our normal rainfall this year, leading to major floods impacting metropolitan areas. People have lost homes and family members. All...
One of my biggest fears when going on a long bike ride is running out of fuel and bonking (a.k.a hitting a wall). It’s a horrible feeling. Your legs feel like jelly, and it seems as if one more rotation of the pedals is impossible....
Every day, we are flooded with data visualizations. Whether it’s a bar chart in a newspaper, an infographic you see online or a pie chart you see in a quarterly earnings report, people are turning numbers into pictures all around us. For those of us...
Speed counts, people! Today’s report consumers expect their dashboards to run as fast as a web page. Now that high speed internet is the standard in business, that’s a lot to compete with. This is why it is essential to optimize each and every dashboard...
Every once in a while, new technologies come along that alter your thinking. In 1982, the spreadsheet radically changed how everyone created budgets. In 2007, Tableau Software changed the way I looked at data. For the first time, the hardware had enough power to analyze large...
In some of my recent posts, I’ve talked (and visualized) about some of the reasons why I love the Tableau community. My first post about the topic was a “thank you” to the Tableau community in general while my second post analyzed community member stats. Continuing...
I met Mike through Twitter some time in 2009. Mike was active in the Tableau community, connecting people from all over the world and answering questions on the Tableau Forums. I did a gig in Ohio in the spring and decided to detour to Cincinnati...
