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...
I’ve been concentrating for weeks on updating my book to include new Tableau 9.0 features. There are a couple of new features that will be featured in this video: The Data Intpreter Ad hoc calculations (with autofill) The video will also show you how to incorporate data blending...
In this article on Tableau Functions, we’ll examine Aggregate Functions. Aggregate Functions are a type of function where values of multiple rows are grouped together as the input to form a single value of more significant meaning, such as a set or list. To access these...
Working on the InterWorks Expert Hotline I come into contact with many clients every day assisting them with all aspects of their Tableau deployment from data preparation to best practice dashboard design all the way through to complex table calculations and Tableau Server tuning. This new series...
I’ve admired Kelly’s Tableau Public work and her blog for several years. Late last year, I was in Vancouver giving a talk. That gave me the opportunity to have dinner with Kelly along with the George Gorczynski, the Tableau Picasso. We talked about data viz for several hours over dinner and had...
In our next Tableau Essentials article on functions, we’ll examine Type Conversion Functions. This group of functions allow you to take the result of any expression and convert it to another specific data type. These are important for preparing some fields for calculation or in...

So, you’ve finally worked out your ETL process using Alteryx and have it exporting a shiny new TDE file. Now what? Using the Run Command tool in Alteryx Designer you can automate the publishing of that TDE to Tableau Server, and here’s how you do...
When last we left our hero, she was complaining mightily about how when you have a calculated field in Tableau, and that field is referenced by another calculated field, things go seriously awry when you replace data sources. Luckily, there is a solution that works...
My career path was illuminated by Stephen Few. Eight years ago, I was looking for a solution to a problem. Stephen’s advice led me to Tableau.
