Waffle charts combine bar charts and pie charts into one chart and compound their problems. While you can see the proportions, precision is lost, especially when the proportions don't fit in one square. And, you still have to decode the color and legend to understand the chart. Also, longer labels will create problems with legend positioning. These charts could be useful with fewer. See more of The Pie Chart on Facebook. Log In. Forgot account? or. Create New Account.
