Donut Chart โ
You can use a donut chart to show the part-to-whole relationships or composition of an element.
Is essentially the same as a pie chart, with the same limitations, but with a couple of advantages:
- You can use the center of the chart to display more information, such as the total value or the labels for each segment.
- Humans are not good at judging angles and area of segments compared to other visual variables, like the height of a bar chart. But by removing the center of the chart, the donut chart helps people to focus on the length of the arc instead.
Usage guidelines โ
When to use โ
Questions you can answer:
- What is the composition of this data? A histogram is also appropriate to visualize the composition of a category.
- What are the proportions relative to the total?
When not to use โ
- If you want to compare the composition of multiple categories, use a stacked bar chart instead.
