Is there any excuse for using a pie chart?

 

 

 

 

 

 

 

 

 

Not really. There is an article by Dan Kopf at Priceonomics on October 5, 2015 titled Should you ever use a pie chart? Pie charts work well for showing the relation between two to five parts and a whole. Not otherwise. He shows a slightly useful and humorous example, the pyramid chart.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

But that pyramid information can be presented equally well via a stacked bar chart in PowerPoint or Excel (either vertical or horizontal), as are shown above.  

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Two funny examples of single-category pie charts from another article at imgur on August 14, 2016 are shown above.
