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...
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...
I have been using Tableau since version 4, initially as a Tableau customer. One of the first things I wanted was to be able to see my data on the move. I didn’t want to see everything, just the basics, a list of green ticks showing...
Quick! Minimize those quick filters! The Tableau Performance Checklist is a guide to assist you in creating the most efficient and fastest dashboards and visualizations possible. The list is drawn from the collective experience of our award-winning Tableau professional services team. We’ve divided the checklist into...
I met Behfar for the first time around 2005. At the time, I was the CFO/CIO for a mid-sized global manufacturing and distribution business. We has just finished divesting our parent company, and most of my team and I had to find technology partners that...
When I build Tableau workbooks, I like to create quick table calculations (such as percent of total) and save those as a calculated field in the Data pane. That way, I don’t have to create that table calculation again if I want to use it...
If you’ve spent any time using Alteryx by now, you probably have a directory full of useful modules. One of the greatest features about Alteryx is that once you have created and tested a module, you can turn that module into a macro or an...
Next week, Alteryx is kicking off their annual Inspire event. We’re excited to be in Boston to talk to people about the amazing things you can do when combining the power of both Alteryx and Tableau. But, while we’re there, we will definitely be checking...
Next, we'll explore the sixth point under the Data section of the Tableau Performance Checklist: “Use extracts wherever possible to accelerate performance. Hide unused and confidential fields. Roll up data granularity by pre-aggregating or filtering. Break hierarchies to only visible dimensions” There are many reasons to utilize extracts...
I met Gregory Lewandowski (aka @lewandog) at the second Tableau Customer Conference. He was wearing this gangster/jazzy fedora, and when I asked him were he got it his answer was that he “knew a guy.” Gregory comes from big-company technology. He works at Cisco and knows...
I haven't had a ton of time to really dig into the new features of Tableau 9, but I did want to start playing with the new Level of Detail (LOD) calculations to see what they could do. The result is simple yet entertaining. The...
In today’s article, we’ll examine User Functions that you can use as part of the Create Calculated Field tool. To access this window, right-click on either the Measure or Dimension window and select Create Calculated Field. Then, select User from the function drop-down menu. The user...
What the world needs now is a ubiquitous schema that is without form and can capture everything. That sounds like Hadoop or some NoSQL capture/archive systems. We want these data sources to be more performant so that they can also support analytical analysis with tools like Tableau. Spark will help that along. What the...
Averages can be weighted too heavily on historical data: models expire, conditions change and behavior evolves. That is why a data analyst keeps a lot of tools in the kit to create an accurate picture of the present day. Window functions are used to remove...
I was recently lucky enough to present at the Berkeley Tableau User Group about how to create a viz that will keep people coming back. I’ll be writing more about this in a later post, but one of the steps I talked about was making your...
This post is also available in: German I am going to start off this blog post with a simple assumption: if you have used Tableau for a while, chances are you’ve read through the release notes on Tableau’s website. You were either checking if an...
