Makeover Monday: The Highest Paid Positions in the NFL

2 comments
Today was a perfect day to practice the “time-boxing” technique I use for makeovers. I worked on this as I headed to Northampton to teach a Tableau Fundamentals course for a customer. The train journey from Euston to Northampton is 57 minutes, and I completed this makeover in 42 minutes.

Ok, here we go. First, the chart to makeover today was by Cork Gaines of Business Insider.


I really like the idea behind this chart: understanding the salary distribution of NFL players by position. However, there are a few problems with this chart:

  • The labels are vertical, making them harder than necessary to read.
  • It took me a while to understand the sorting; the chart appears to be sorted by average salary.
  • The salaries are only for the top 10 in each position, which means the min, avg and max are all relative to those 10 players.
  • The labelling feels like it’s cluttering the chart.

To address these concerns, I’ve created the viz below. In my version, I’ve made the following changes:

  • Changed the labels to horizontal
  • Added options for sorting the viz by any of the metrics and allowing the user to pick a sort order
  • Added a filter for the team the position belongs to
  • Changed the chart from a bar chart to a dot plot/DNA chart
  • Moved the labels into the middle of the dots, where they fit, and removed the $ symbols
  • Changed the colours to use the offical NFL colours

This was a pretty simple and quick makeover that I feel provides a much more meaningful and insightful visualisation.

  1. Hi Andy!
    First of all, congratulations for all your help and work already did helping people to know better Tableau. You have done a great work. No question about it! I have learned a lot from you.
    Any chance that you can explain step by step (or by a video) how do you get this visualization done?

    I would really appreciate if you do this because knowing how to get this visualization will help me a lot in my present and futures jobs assignments.

    I am looking forward for your answer,

    HA

    1. Hi HA. I already created a video for how to create these charts at the link below. The only difference is that the one above has 3 measures in play instead of 2. The technique is the same though. You should also download the workbook and try to dissect it yourself. That's a great way to learn. http://vizwiz.blogspot.co.uk/2015/06/dnacharts.html
