Lying with bar charts

September 8, 2014 Leave a comment

I found this image in the newspaper a few months ago

The main problem with this visualization is that doubling the value doubles the height AND width of the bone, making it look like a four-fold increase.

Moral of the story? Use fixed width bars and only vary the height. Sorry USA Today et al who create these garbage charts.
