The pie chart displays reduced series, or values in a series, from one or more queries, as they relate to each other, in the form of slices of a pie. The arc length, area and central angle of a slice are all proportional to the slices value, as it relates to the sum of all values. This type of chart is best used when you want a quick comparison of a small set of values in an aesthetically pleasing form.
Select a calculation to reduce each series when Calculate has been selected. For information about available calculations, refer to the [Calculation list]({{< relref "../panels/reference-calculation-types.md" >}}).
Select which field or fields to display in the visualization. Each field name is available on the list, or you can select one of the following options:
Select labels to display on the pie chart. You can select more than one.
- **Name -** The series or field name.
- **Percent -** The percentage of the whole.
- **Value -** The raw numerical value.
Labels are displayed in white over the body of the chart. You might need to select darker chart colors to make them more visible. Long names or numbers might be clipped.
The following example shows a pie chart with **Name** and **Percent** labels displayed.
