I’m going to take a different approach to this new Deep Dive series, differently than I have with the past articles I have written. Previous Deep Dives focused on a suite of functionalities and use cases associated with a particular feature of Tableau Desktop, such as...

In most Tableau training sessions, we want to use large datasets to provide meaningful insights. It can be hard, however, to get a large dataset, as per our requirements. How about generating billions of rows of dataset in a few hours? I used Python script...
I have the honor - and pleasure? - of kicking off our first ever Webcast Friday. I show a couple of ways I use Tableau to analyze web traffic from Apache. The real benefit of using Tableau here is that I can easily spot trends or track issues...
Unlike JDBC, ODBC is language-independent. ODBC is an open interface that can be used to communicate with databases. All you should do is create an ODBC connection to EXASOL database in your system. For windows, follow these steps to add ODBC creation. Here is an example...
Wondering about how to use data from EXASOL in analytical tools? EXASOL integrates with most analytical tools. Below is an example of how to connect to EXASOL from R and create a beautiful cluster plot. In this example, I used JDBC which is an interface used by Java applications...
Some of my best memories have been had on the ski slopes! My brother, Matt, and I are unique in loving the kind of terrain most people loathe – moguls. We both love the feeling of hitting our rhythm in and out of densely packed...
EXASOL offers the world’s fastest in-memory analytic database. It is built from scratch to offer the highest performance and scalability for in-memory analytics. You can now build in-memory data analytics in less than 15 minutes. Forget about maintaining and investing on expensive analytical tools used for...
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...
