One of my least favorite phrases currently being used in the analytics world is “data science.” This is ironic since “data science” is in my official InterWorks job title. But every time I hear the phrase, I get a little knot in my stomach similar to...
InterWorks has created several blog series targeting Tableau users, including the "Tableau Essentials" series, the "Tableau Performance Checklist" and my own "Tableau Deep Dives." These articles are among the most popular on our blog and our readers are always asking for more content on how...
Tableau isn't just a useful tool for visualising and analysing data. There's no doubt it has enabled me to improve and optimise my team, but there's another benefit I did not initially appreciate when I first began using Tableau. Coming from the world of Excel,...
It might sound controversial, but a common practice in my family (and many families throughout Louisiana) was something called "hotsaucing." What exactly is that? When your a kid acts up, you punish them by making them eat a little bit of hot sauce. The jury is...
Table calculations are one of the hardest functions to understand in Tableau Desktop. A lot of us are guilty of clicking through every single option on the table calculation window until we find something that looks right. There is a lot of great material out...
I finally cracked and decided to shove everything in my personal life aside for the next few months to take on Udacity’s Machine Learning Nanodegree Program. Goodbye video games and ice-cold beer! On second thought, beer, you should stay. I might require a cheerleader. Jokes aside, I’ve had my...
While teaching a Desktop I and II Accelerated class last week in Perth, I got an interesting question from a Tableau student named Clint. "Can you make a highlight dynamic so that it will highlight just the top 10 or top 20?" When it comes to Tableau, the...
Returning to Podcast Your Data! this week is Alberto Cairo! You may remember him from one of our very first podcasts over a year ago. As the Knight Chair of Visual Journalism at the University of Miami, he has in-depth experience with the state of...
As purveyors of analytics, we often come against the buttresses of change aversion. Nowhere is this more prevalent than in the lack of acceptance of Tableau tooltips. How often do you present your end users with a powerful and dynamic viz only to be met with, “But where...
It's a data nerd's favorite time of year! That's right, the 2017 Tableau Conference has come and gone with all the updates and announcements you crave. Don't forget that you can be part of the action via Tableau's conference site, where videos from keynotes and sessions are available...
While working with a recent client, we tried to answer which product categories their business should keep investing in and which categories are not worth the effort of selling. At this point, I remembered the strategic marketing classes I took during my time at university....
Another Autumn another update from the good people at Tableau. Tableau 10.4 acts as the third major update of the software within the 2017 calendar year. Let’s have a look at the main new features of 10.4 on both Tableau Server and Tableau Desktop that...
So, a little about me, the author: I'm a chartered accountant and my background is in building finance functions and creating financial performance analysis reporting functions. I trained in a public practice and, after around six years, moved into industry. I've been working in industry...

This week’s PYD! is extra special as we have not one, but two Zen Masters! Okay, one current and one former, but still! InterWorks’ Dan Murray chats with Piedmont Healthcare’s Director of Business Intelligence, Mark Jackson. They’re long-time acquaintances and jump right into the data talk!...
Quick table calculations in Tableau are a great way to understand and visualise relationships between measure values. The most frequently used calculation types (running total, difference and percent difference) are core metrics in most financial management reports. What Are Ad Hoc Calculations? Quick table calculations were created to...
Let me start off by asking two questions: Why should we learn to code? Why use Python? If you type either question in Google, you’ll receive a long list of differentiating, yet persuasive answers. Knowing how to code is an empowering feeling and skill. From my perspective as a data...
As the first post in a series about Tableau Server on Linux, I wanted to share a quick note and some promising results of performance testing in the upcoming release. The TL;DR Tableau Server on Linux = Joy. Median dashboard load times were cut 40-60% compared to...
The ultimate goal of this Deep Dive on Dashboard Design is to guide Tableau Desktop users on how to create a dashboard from start to finish. That conversation would not be complete unless we went the extra mile. I’m talking about publishing the dashboard of course....
If you are not already familiar with cross joins, you may want to read through my first post in this series for another use case. In this article, I will further define and expand on cross joins. What's a Cross Join? Sometimes we are stuck working with...
