Pie chart
Pie charts show categories as a proportion or a percentage of the whole. Use pie charts to show the composition of categorical data with each segment proportional to the quantity it represents.
When do you use it?
Pie charts are effective when comparing parts of a whole for a static period. They do not show change over time.
Consider using a pie chart if you are working with:
- one data set pie charts are effective for categorizing and comparing one data set
- positive values pie charts cannot display zeros and can be confusing when working with negative values
- seven or fewer categories it becomes increasingly difficult to perceive the relative size of each segment when working with more than seven categories
Examples
