# Pie & donut

> Show how a single measure is distributed across a small number of categories.

Pie charts divide a circle into slices proportional to each category's share of the total. Best for communicating part-to-whole proportions to a broad audience when you have a small number of clearly distinct categories (typically five or fewer).

## Variants

### Pie

Standard filled circle. Each slice's arc length is proportional to its value.

### Donut

A pie with a hollow center. Switch to it with the **Shape** control in the Fields tab — a two-option toggle between **Pie** and **Donut**. The hollow center can be used to surface a summary value via a [KPI](/docs/explore-analyze/charts/chart-types/kpi) tile on a dashboard, or simply to reduce visual density.

## Rings

Add more than one dimension to the query and the chart draws them as **concentric rings** instead of a single ring of slices — the first dimension is the innermost ring, and each additional dimension nests around it.

Drag rows in the **Rings** list (Fields tab) to reorder the nesting. The innermost ring also drives slice color.

<Note>
  Only the outermost ring's values are guaranteed to be accurate for a non-additive measure (e.g. a distinct count) — inner rings sum the measure across the outer rings, which can overstate it. A warning appears in the panel when this applies.
</Note>

## Measure

The **Measure** field sizes the arcs — pick the measure whose value determines each slice's angle.

## Data labels

Configure labels on the Style tab, under **Data labels**. Each atom is an independent toggle:

| Atom         | Description                                     |
| ------------ | ----------------------------------------------- |
| **Category** | The dimension value the slice represents        |
| **Value**    | The measure value, with its own number format   |
| **Percent**  | Share of the total, with its own percent format |

Category and Value are on by default. Toggling the first atom on adds the label layer to the chart; toggling the last one off removes it.

Additional controls appear once at least one atom is on:

| Setting           | Description                                                                                                                                                                                              |
| ----------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| **Position**      | Inside or outside the slice                                                                                                                                                                              |
| **Labeled rings** | For charts with [rings](#rings): show labels on the outer ring only, or on all rings. Inner rings only ever show the Category atom — Value and Percent need per-ring aggregation, which isn't supported. |
| **Font size**     | Label text size, in pixels                                                                                                                                                                               |

## Tooltips

Choose which fields appear in the tooltip from the **Tooltips** field picker in the Fields tab — none, all fields, or a specific selection.

## Color and slice ordering

Slices are colored using the active [color palette](/docs/explore-analyze/charts/configuration/color-and-stacking) in palette order, matched to the sort order of your query results. To change which slice appears first, adjust the sort in the results table. For a chart with [rings](#rings), the innermost ring's dimension drives slice color.
