Pie and donut charts

Pie chart

Donut chart

A pie chart shows proportions between categories by dividing a circle (pie) into proportional segments (slices). The full circle represents 100% of the data. In the pie charts, you evaluate the pieces according to their areas.

The donut chart is similar to the pie chart, except that it does not have a central point, and you evaluate each piece according to its length. The donut chart is similar to a stacked bar chart that has been curled around itself.

When to use

Use a pie or donut chart to compare categories that are parts of a whole. The categories on a chart must be mutually exclusive and not overlapping. For example, a pie or donut chart can be used to compare the profitability of different departments inside a company. However, a pie or a donut chart is not suitable for comparing different companies to each other that are not parts of a whole (because the number of companies is not limited).

For better chart readability, use data with up to five categories that are represented by slices. A pie or a donut chart is not useful if the values are close to each other. For example, slices for 32%, 33%, and 35% look very similar.

Data requirements

To build any of these charts, define the data fields as follows:

  • Dimension – One dimension
  • Measure – One measure
  • Tooltip – (Optional) One or more measures
  • Trellis – (Optional) One dimension

Use case

The following chart shows how each department contributes as percentages to the whole 100% of gross sales.

The same data is visualized by using the donut chart.
