Overview Tableau 9.0 includes a built-in data prepping tool that makes reshaping survey data so it plays nicely with Tableau a much smoother experience than using the Tableau Excel add-in. While this new feature won’t replace by trusty copy of Alteryx (for reasons that I explain later in this post) there are many occasions where [...]
Overview Note: I based my Tableau Conference 2015 presentation on this blog post. You can download a PDF of the presentation and the Tableau packaged workbook. Click here to see a video of the presentation. Earlier this year one of my clients was updating a collection of survey data dashboards and they wanted to revisit the [...]
Finally, a good use for packed bubbles! The Problem I recently received a query from a client on how to compare responses to one question with responses to another question when both questions have possible LIkert values of 1, 2, 3, 4, and 5. That is, if you have a collection of questions like this: [...]
Overview In my experience the number one impediment to success with Tableau is getting data in a format that plays nicely with Tableau. Alteryx is a combination ETL (extract, transform, load), geospatial, and statistical modeling solution that just may solve this “getting-the-data-right” problem. And it plays very nicely with Tableau. In this blog I will [...]
... and some thoughts on the evolving art and science of visualizing data I tend to gravitate towards occupations that are hard to explain. I started my professional life, and continue to be, a music arranger and orchestrator. I can tell by people’s perplexed looks that they are wondering if I’m the guy that decides where [...]
Overview I’ve had a spate of requests from clients to show how survey responses rank across different categories and I’ve come up with a way that makes it very easy to see where the big stories are. Note that this approach works for any measure that can be ranked, not just survey responses. Let’s see [...]
In this installment we’ll look at Utah State University’s publication of student engagement results. Utah State is one of many collegiate institutions that have participated in NSSE’s national survey of student engagement (see http://nsse.iub.edu/ and http://nsse.iub.edu/html/about.cfm). Special thanks to Allan Walker for making the underlying data available to me. Note: I've published four sets of [...]
Note: This post is dated but contains useful information. I've discovered some better ways to handle this but haven't blogged about it yet. Feel free to nag me and I'll either write the post or conduct a screen-sharing session. Overview Note: If you have not already done so, please review Part 1, Part 2, and [...]
Overview I was stuck earlier this month trying to cajole Tableau into doing something I needed it to do so I contacted my friend Joe Mako. When it comes to Tableau, Joe is the "guru's guru." (Joe was the person that showed me how to create filled maps in Tableau before Tableau had native support [...]
Note: While the information in this blog is useful, I've discovered some better ways to perform intra-question analysis; I just haven't blogged about them yet. Feel free to nag me. January 3, 2018 update. I've written a two-part post that explores better ways to conduct intra-question analysis. Please see this post. Overview So, I thought I [...]
