[Excel] How to make a hemicycle plot

Hemicycle charts are useful to communicate how the results of elections translate into number of MEP. The hemicycle replicates the shape of many parliament chambers.

Hemicycle-shaped Excel chart
Hemicycle plots are useful to display results of general elections.

Design notes

  • Label the slices directly
  • Use political party colors
  • Since you have to include a hidden hemicycle (the lower part) you can’t use percentages calculated by Excel. Get the labels from a range where those percentages are calculated.
