When someone misleads you with a dual-axis chart, fight back! Data Viz Done Right!

My good friend Joe Mako published this version of the chart I ranted about earlier today.  Now THIS chart tells the story correctly.

The goods:

  • 2001 – The red line is at 88%, while the blue line is at 79%
  • 2011 - The red line and blue line are both at about 114%

No dual-axis needed!  Chart junk be gone!  What a difference!
