# Pie Charts

> The pie chart divides data into slices to illustrate numerical proportion, and Invoca's default pie chart is shaped like a doughnut.

A pie (or circle) chart is a statistical graphic that divides data into slices to illustrate numerical proportion — the arc length of a slice is proportional to the quantity it represents. The pie chart is a classic chart type that displays your search in a circle; Invoca's default pie chart displays data in the shape of a doughnut, or thick ring.

Your search needs at least one attribute and one Measure to be represented as a pie chart, and the attribute column must have fewer than 250 values.

## How pie charts divide data

Pie charts divide your data into sectors that each represent a proportion of a whole circle. To display the exact values of each slice along with percentages, select the **Chart configuration** icon > **Settings** > **All labels**.

## Pie in pie charts

A pie in pie chart compares more than one component of an attribute, showing two concentric pie charts that compare different Measures. To create one, assign two different Measures to the **Size** section under **Edit chart configuration**.

## Color customization

You can customize the colors of each pie using the **Chart configuration** icon:

1. Click the **Chart configuration** icon.
2. From the Edit chart window, click the attribute under **Category**.
3. Click the color chip next to each item you want to change, or enter a Hex value directly. Changes save immediately.

If you have a pie in pie chart, changing a color updates both widgets that apply to that attribute value.

## Limitations

Pie charts do **not** support conditional formatting.
