I’m sure we can all relate to the following scenario: A client or boss requests a change to a query, so you plop your hands on the keyboard and start cranking out some SQL. At the end of your last revision, you’re about 75% sure...
We’ve all been there: You grind away on a dashboard and spend hours to perfect the look and feel. Slowly, you notice the creeping spinning circle running longer and longer – “but that’s a problem for future me,” you tell yourself. Then comes the demo....
If you’ve evolved to the point where your dashboards are crunching gobs of data and are powerful enough to warrant numerous filters and parameters to drill down for myriad uses, you may have been annoyed with waiting for each filter to be applied before being...
It’s August again, which means it’s still hot, but football is here! Personally, I’ve been enjoying a ton of baseball and the gobsmackload of home runs we’re seeing. The World Cup was also simply outstanding start to finish, but football in America means only one thing:...
I love cars. The way they sound, the way the smell and the way they feel when you're cruising down long roads. But sometimes, finding the right car for the experience can be troublesome. Car shopping is a lot like dating. There is a lot...

Recently, I was required to prepare data in Alteryx and output it into a .Hyper file to create a Tableau workbook. The data that was being utilised looked at past sales and potential future sales. The dataset was a very large dataset, over 20 million...
Until now in Portals for Tableau, we’ve basically forced you to allow your users to download a crosstab of each dashboard by using the Export CSV button. If you didn’t want to let your users access this button, the only solution was to hide it with...
Labels on line charts can get messy. To reduce clutter, we are often are faced with reducing the labels to only the end of the line or simply removing the labels altogether. Here’s a simple trick that provides some flexibility with labels on lines. This...
When we hear waterfall charts, we expect to see a visualization showcasing the cumulative effect across various categorical-based data to see the positive or negative change between them. But we have not talked about using a waterfall chart to represent parts of the whole. Pie...
Question: "I want to build a Sankey diagram with my survey data, but I don’t know how to even start this. I want to be able to see someone’s response before exposure and after exposure to the test object we are surveying on. Could we hop...
Every single day, I get emails from former students asking for help with everything from visual best practices to calculated fields. Sometimes the questions are quick while others require more thought. Some may be deceptively simple questions that turn into something more complicated than first thought. What...
Portals for Tableau are created and maintained by lazy people. Many people that administer and use Portals for Tableau are also lazy people. This is not a bad thing. In fact, I would argue it’s dumb to do more work than is necessary. As a...
Matillion – cool name, cool tech. Before I get into the actual tech, I’ve just got to comment: Who comes up with all these company names? It seems like in the entire tech industry, the Coolest Names Award is going to big data. Okay back...
The point of the #MakeoverMonday project is to take an existing data visualization and improve it. But how can you improve anything that "The Economist" creates? They have such a knack for breaking down complicated topics into clean, clear and concise visualizations. So, when I...
The idea behind this blog post is to document a novel approach I have come up with to allow for date selection in a report that defaults to the most recent time frame. There are multiple ways this sort of problem can be solved. My...
Question: "I’ve established the data relationship, but the number still won’t show and I still get this error. What am I doing wrong?" Blending is one of those features that we see many issues with. Some users don’t realize they’ve started a blend while others may have...
Picture this: You are trying to build a sales dashboard in Tableau Desktop to show your boss how great you are. But hey, there is one issue: The data you have is currently in a structure not suitable for Tableau Desktop. You need to crosstab...
Normally when I build a dashboard, I approach it like a funnel: I start with the big picture first and then narrow into more specific details. This allows viewers to establish context and get the most important insights right from the start and then choose...
