# Circular Charts (Pie, Doughnut, Rose)

> Set up Pie, Doughnut, and Rose charts with dimension and measure.

Pie, Doughnut, and Rose charts show **parts of a whole**. Each uses a **dimension** (categories) and a **measure** (values).

## Chart Types

| Chart        | Use case                                                   |
| ------------ | ---------------------------------------------------------- |
| **Pie**      | Proportions; few categories (e.g., market share by region) |
| **Doughnut** | Same as pie with center hollow                             |
| **Rose**     | Similar to pie; radius or area mode for different emphasis |

## Data Requirements

* One **dimension** (categories, e.g., region, product, segment)
* One **measure** (values, e.g., SUM of sales, COUNT of orders)

## How to Set Up

1. Create or edit a metric. Add one dimension and one measure.
2. Click the **Charts** icon and choose **Pie**, **Doughnut**, or **Rose**.
3. Click the **Settings** icon, then open **Chart types** → **Chart properties**.
4. Under **Required Axis**:
   * **Dimension**: Column for categories (sectors).
   * **Measure**: Column for values (sector sizes).

## Rose Chart Options

For **Rose** charts, use the **Appearance** tab in **Settings**:

* **Rose type**:
  * **Radius** — Sector radius reflects value (absolute comparisons).
  * **Area** — Sector area reflects value (proportional).

## Label and Interaction

In **Appearance** → **Chart Label**:

* **Position**: Outside, Inside, or Hidden.
* **Show dimension**: Include category name in labels.
* **Selected mode**: Single, Multiple, or Series (which sectors expand on click).
* **Selected offset**: Distance (px) when a sector is selected.
