2023 Week 8: Can you build a comet chart as an alternative to a side-by-side bar chart?


The theme for February 2023 has been alternatives. This week I present an alternative (and trust me, there are many other alternatives) to my least favorite chart: the side-by-side bar chart.

The reason this chart is so difficult for me is because it takes up a lot of space and when I am doing comparisons of numbers I’ve got to cross so many other value and dimensions. I want to make comparisons faster. That’s why sometimes I use a comet chart.


  • Dashboard Size: 800 x 700px
  • 1 sheet
  • Create a comet plot that shows sales for 2021 and 2022 by sub-category.
  • The narrow part of the comet should be 2021 sales
  • The wide part of the comet should be 2022 sales
  • The labels should be 2022 sales
  • Match the size of the comet around the circle
  • The color represents the direction of change in sales from 2021 to 2022. The red represents a decrease in sales
  • Match the formatting
  • ADVANCED: Table Calculations only
