Overview I really am not “out to get” Texas. Yes, I have previously published a visual study tracking STDs, HIV, and AIDS in Texas, which in turn led to some blog posts on the subject, but one of the main reasons for focusing on Texas was that the data I needed were readily available and [...]
Note: This post is very dated. Please see the YouTube video from the Tableau 2014 conference and the Visualizing Survey Data page for more up-to-date information. Overview In my previous blog post I discussed how to reshape your survey data so that it plays nicely with Tableau. In this post we’ll explore how to visualize [...]
Note: This blog post is rather dated. While it does stress the importance of reshaping the data it only shows how to do this using the Tableau add-in for Excel and doesn't discuss the optimal format for survey data. The post also doesn't address how to combine survey results downloaded in a numeric format with survey [...]
Overview Full Disclosure – my former company, WexTech Systems, developed and marketed the first commercial online help authoring tool, Doc-To-Help. I use online assistance a lot and expect it to be, well, helpful. Is it me, or has the quality of online help / user assistance declined in the past few years? For example, when [...]
Overview I received a number of comments from my last post (see https://www.datarevelations.com/likert-scale-nirvana.html) including what I think is a better approach for staggered Likert scale visualizations from Joe Mako. Joe’s approach with various “kitchen sink” added functionality is shown in the interactive dashboard below. Notice that you can control whether neutral values are displayed, sorting, [...]
Overview I’ve written a lot about this subject (see https://www.datarevelations.com/the-likert-question-question.html and https://www.datarevelations.com/a-little-more-on-likert-scale-questions.html) but some recent discussions with friends / colleagues Joe Mako and Naomi Robbins (along with some long plane rides to and from the Midwest) encouraged me to see how difficult it would be to create a “staggered” Likert scale chart like the one [...]
What’s Going to Happen when the Clinics Close? I’ve had a lot of conversations this past week regarding my data visualization tracking STDs, HIV, and AIDS in Texas from 2006 to 2010 (see http://bit.ly/r57qeR.) One of the bigger questions that may have been overlooked in my accompanying blog post is what is going to happen [...]
You all know I love Tableau, yes? We're cool with that... ... but... There are times when I see Tableau guiding people to make less than ideal visualizations; situations where your have to grapple with the tool to get better results. A good example may be found at the Tableau Public blog. Here's a screen [...]
Overview The Texas State Legislature’s recent and sweeping funding cuts to all family planning organizations – including the complete defunding of Planned Parenthood – has lead Data Revelations to examine historical data on sexually-transmitted diseases (STDs) and HIV / AIDS and suggest what the case count and incidence rates will look like in the near [...]
Some thoughts on Size, Color, Usability, and Engagement I am consumed by doing what I can to make sure that my Tableau visualizations (both public and for clients) are, well, consumed. While Tableau excels at helping people explore data and turn information into insights, it is still all too easy to create dashboards that neither [...]
