# Radial Chart Rings

Three concentric activity rings showing move, exercise and stand progress toward their goals.

Radial Chart Rings is an open-source mobile chart from suiss/uim, drawn with react-native-svg for React Native and Expo, with SwiftUI and Jetpack Compose versions built from the same design tokens. The @esuiss/uim CLI copies its source into your project, so you own the code.

Three rings drawn with `Svg` circles colored through `ChartPalette`. Each entry in `rings` has a value and a goal, and the filled arc is capped at a full circle. The whole graphic is one accessible image whose label lists each ring's value and goal. Nothing is interactive.

## Installation

```bash title="Terminal"
npx @esuiss/uim@latest add radial-chart-rings
```

```bash title="Terminal"
npx @esuiss/uim@latest add radial-chart-rings --platform swift
```

```bash title="Terminal"
npx @esuiss/uim@latest add radial-chart-rings --platform kotlin
```

The CLI also adds what it builds on: [Card](/docs/components/card), [Chart](/docs/components/chart).

### Manual

**Uniwind**

1. Install the dependencies:

```bash title="Terminal"
npx expo install react-native-svg
```

2. Add the pieces it builds on: [Card](/docs/components/card), [Chart](/docs/components/chart).

3. Copy the source into `components/charts/radial-chart-rings.tsx`:

                    const circumference = 2 * Math.PI * radius

4. Update the import paths to match your project.

**SwiftUI**

1. Target iOS 17 or later.

2. Copy the theme files every view uses:

```swift title="swift/Theme/Theme.swift"

    green = CGFloat((hex >> 8) & 0xFF) / 255
    blue = CGFloat(hex & 0xFF) / 255
    self.alpha = alpha
  }

  var uiColor: UIColor {
    UIColor(red: red, green: green, blue: blue, alpha: alpha)

3. Copy the source and every file it uses:

4. Add the files to your app target.

**Jetpack Compose**

1. Set `minSdk` to 24 or higher and add the dependencies:

```kotlin title="build.gradle.kts"
implementation(platform("androidx.compose:compose-bom:2026.09.00"))
implementation("androidx.compose.foundation:foundation")
implementation("androidx.compose.ui:ui")
```

2. Copy the theme files every view uses:

4. Update the `com.esuiss.ui` package names to match your project.

## Usage

```tsx
import { RadialChartRings } from "@/components/charts/radial-chart-rings"
```

```tsx
<RadialChartRings />
```

Replace the values, goals and colors in `rings`, and change `SIZE` and `BAR` to resize the rings. The component takes no props.
