Makeover Monday: The Highest Paid Positions in the NFL

What is Wrong With This Chart?

“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” - Andy

• 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” - Andy

• 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 colors to use the official NFL colors

A Practical Introduction to Context Filters in Tableau

http://paintbynumbersblog.blogspot.com/2015/11/lets-put-some-things-into-context.html

“In simple terms, putting a filter in context ensures that all other filters are dependent on that Context Filter. Tableau filters otherwise act independently and this is a useful feature, but may sometimes mean that filtering doesn't do what you might first expect it to do.”

Generating High Resolution Images of Tableau Views

http://blog.databender.net/2015/11/24/generating-high-resolution-images-of-tableau-views/

http://<server>/vizql/sheetimage/<view_id>?:pixelratio=2

:pixelratio=1This is the standard resolution for most devices.

:pixelratio=2This is the resolution we generate automatically for retina devices. (Max for Maps)

:pixelratio=4But we can take this higher…

:pixelratio=10Much, much higher.

Override Action Filters using… Other Action Filters

“The trick is to add an arbitrary field to the action filter that can be passed by all the action filters. As you can see in the screenshot below, I created a field called "Filter Link" and gave it a value of 1. I placed it in all the source views so that the action filter will include it when passing the filter values to the destination view. Note that the pill has to be blue.”
