Tornado Visual

Devin Knight looks at the Tornado chart:

  • The Tornado has a few limitation that should be aware of before using

    • If there’s a legend value it should only have 2 distinct values

    • Each distinct category values is a separate bar with left or right parts

    • Alternatively, you can have two measure values and compare them without  a legend

I’m split on whether I like the tornado or not.  It is intuitive and information-dense, which are two major factors in its favor.  It is, however, difficult to read and compare.  This seems like a useful “big picture” chart, but you’d want to organize the data in a different way when you start drilling down.
