How To: Coxcomb Charts in Tableau

In my earlier post, I mentioned how I decided to use Coxcomb charts in my latest viz. Before I go any further, I want to give credit to Bora Beran for his original post on creating these chart types in Tableau as well as providing a sample workbook. All of the custom formulas used in creating the charts are to his credit.

At the request of several members of the community, here is a step-by-step guide (although there may be a better way, but oh well) on how to create them in Tableau.

For this tutorial, we will be using the following file:¬†2016_Clemson_Yards_by_Game. This file represents Clemson’s ¬†total passing and rushing yards per game for the 2016-17 season. The goal for our visualization will be to create a coxcomb chart that shows the comparison between passing yards and total yards by opponent (by design, it will show us the Clemson’s disparity between passing and rushing offense by opponent for the 2016 season).

CFP Initial Top 4: A Twenty Year History

For my first Tableau Public viz in over two years, I decided that I wanted to do something different, unique. While I may have not been active in the community, I still managed to keep up with the awesome work that was being published up to Tableau Public. From what I have seen, not many people choose to use Coxcomb charts in their visualizations. While these chart types are very unique (thanks Florence Nightingale), they have very specific use cases. In order to do something unique, I thought that I would use them to create a viz that shows the total wins per season for the teams that were in the initial top 4 of this year’s College Football Playoff rankings. I also used the awesome Viz-In-Tooltip feature to allow users to hover over a “slice” (each one representing a season) and see that team’s schedule and results for that season; along with a couple other things of note. For those wondering, yes, I will be doing a simple how-to to post on how to create these in Tableau in the next couple days. Check it out below…

I’m back…

Wow, it has been a while (too long) since I have published a blog post. For the ones that don’t know me, my name is Matt Cobb and I am currently the Director of Business Intelligence and Data Analytics with the Clemson University Athletics Department (Go Tigers!!!). I have been using Tableau since 2012 (Tableau 6) and owe much of my career progression to it. Several things have happened since the last time I was active in the Tableau community. I became a father, got a new job and started grad school all in the past couple years. As part of my new beginning, I felt that a “rebrand” was in order (my old blog used to be called Mr. Data Jockey, and for those of you that were at TC14 in Seattle, I came up with that after seeing Sir Mix-a-lot live. Where do you guys think Matt Chambers got his awesome blog name?). So without further ado, welcome to my new blog, Down For The Count. My goal with this blog is to share interesting data visualizations, stories and tips that will help add value to the Tableau Community. As I am one of the few people working in an analytical role within a sports organization, sports data is my first love and lot of my material will be sports related (I plan to do other things though, stay tuned…).
