There’s been a lot of coverage of wildfires in the United States this year, particularly in the Pacific Northwest, where some of the largest fires are consuming hundreds of thousands of acres. To bring some context, I scraped data from the US Forest Service’s website...
Approximately 8.2 million people live within the five boroughs that make up New York City. Every year, thousands of accidents occur due to a multitude of contributing factors. NYPD collects information about each of those accidents and provides it for public use on nycopendata.socrata.com. We...
The rule that we’ll cover today is: "Limit custom SQL in live connections as they can be inefficient. Where possible, create a view on the database server to implement your custom SQL and connect Tableau to your view." In other environments and in other tools, using your...
Over the last twenty years, video games have become a cultural force in America. From movie spin-offs to t-shirts at Target, it's almost impossible not to be touched by the gaming industry every day, even if you don't consider yourself a "gamer." In this period...
Tableau Driver's Ed is a new blog series in which we explain InterWorks' unique take on Tableau Drive, a new methodology for enabling self-serve BI in the enterprise. For the full list of posts, check out the Tableau Driver's Ed channel. “Data, I think, is one of the most...
It’s entirely possible that one must be a country music fan (Kenny Chesney, generally, and his song “No Shirt, No Shoes, No Problem,” specifically) to understand the reference in the title. I’ll grant that up front! But whether you are or aren’t a fan, when you...
The final topic in Filtering addresses when and when not to use user filters and how it can slow down your visualization: "Don’t be lazy with user filters. Security by user filters can impact performance on Tableau Server as the server cannot share connections and query...
.syntaxhighlighter code{font-size:0.9em!important;} The Problem During a recent engagement a client asked a question I hear occasionally regarding Tableau which basically boiled down to: "How do I show marks for the percentile ranks of my customers by Sales?" The client wanted to aggregate their measure, we're using Superstore Sales here,...
Keeping track of the growing number and types of database products is a full-time chore. This week I spent a few days in Vail, Colorado at the Pacific Crest Global Technology Forum. This is the 17th year that Pacific Crest Securities has sponsored the event—bringing...
Earlier this year, a good friend of mine, who is responsible for me working at InterWorks, wrote a blog post about his personal weight loss journey and how he uses data to enhance his training efficiency. Brian's post really made an impact internally at InterWorks. We saw someone very...
Just a few days ago, I had the privilege of attending and presenting at the latest Baton Rouge TUG meeting. As an LSU alumnus (Geaux Tigers!), I was thrilled at the opportunity. It was also great to see how much the Tableau community has grown...
I was plugging away at various tasks yesterday when I received a fun notification from Windows: “You have low disk space on C:” This isn’t unusual, as I have an SSD on my C: drive and have to clean it up every now again. I was surprised...
When you think of Oklahoma, what comes to mind? Maybe you think of cowboys, farming, Native American culture or the oil and gas industry. All of those are common answers, but there’s something associated with Oklahoma’s identity more than anything else: tornados. This weather phenomenon definitely...
Matthew is relatively new to the Tableau world (with a little over two years in the Tableau sphere) and I have to admit, I didn’t know about him and didn’t meet him until the annual Tableau Conference last year in Seattle. Like a bullet, he...
“Is an MBA worth the investment? The answer to this question is the standard MBA answer: It depends. The worth of an MBA depends on a variety of factors. Perhaps the most important of these is return on investment (ROI), which can vary greatly between MBA programs. Other key...
Earlier this week, Tableau Software published a security advisory detailing a security vulnerability affecting Tableau Server. This vulnerability enables a user to impersonate a different user, which could allow them to access sensitive dashboards/data or to perform actions that they normally wouldn't be able to perform. Affected versions of...
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’ve been aware of Juice since before my days as a consultant. Around 2007, I found Juice Analytics because they were serving-up some very useful blog posts on data visualization before it was a household word. In particular, I loved an Excel add-on they had called the Chart...
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...
