Overview I’m a big fan of Andy Kriebel’s and Andy Cotgreave’s Makeover Monday challenge. For those of you not familiar with this, each week Kriebel and Cotgreave find an existing visualization / data set and ask the data visualization community to come up with alternative ways to present the same data. As Cotgreave points out [...]
Overview As I’m mentioned before the number one impediment to success with visualizing survey data in Tableau is getting the data in the right format so you can do all the dazzling things you want to do. Up until very recently none of the survey tools vendors had done anything to make things easy so [...]
Overview I spend a lot of time with survey data and much of this data revolves around gauging people’s sentiments and tendencies using either a Likert Scale or a Net Promoter Score (NPS) type of thing. Examples Here’s an example of gauging sentiment using a 5-point Likert scale. Indicate how satisfied you are with the [...]
Overview In an October 2015 meeting of the Tableau Zen Masters each Zen Master was asked to name his / her favorite thing about Tableau. Most people started by saying “well, besides the community, my favorite thing is…” At the time I said “undo”. Don’t laugh. Let’s not take it for granted that with Tableau [...]

Understanding the workflow Here’s the Alteryx workflow that will get the data in the format we want. Figure 9 -- Alteryx workflow for getting the survey data [...]
Overview In writing about visualizing survey data using Tableau I’ve found that the number one impediment to success is getting the data in the right format. In accompanying posts I'll explain how to get this done using Tableau Prep, Alteryx, Easymorph, and Tableau 10.x. What do I mean by “just so”? When I deal with survey data [...]
Overview I recently wrote about emotional vs. accurate comparisons and several people questioned whether the word “emotional” was appropriate. (Several people questioned my assertions, too. You can read their comments here.) For this discussion I’ll use the term “engagement” in place of “emotion” and we’ll look into the challenges of creating public-facing visualizations that attract [...]
