If you create reports frequently, I bet you've used Pie Charts at some point.
Pie Charts aren't the best when it comes to data visualization, mainly because the human brain is not efficient at comparing the length of curved lines or internal angles of pies.Plus, it's tasking for the eye to jump quickly from the pie to the legend to connect each pie to its category.
When you need to compare the % share of different categories in a field, you might feel there's no other way than using a pie chart, but here, I'm going to show you one of my favorite alternatives:
A Horizontal Bar Chart
Creating a horizontal bar chart is easy, and it's better than a pie chart because it's easier to interpret.
The trick is getting each bar to appear in a different color, and to show the percentage of total rather than the actual metric on each bar.
