# Radial Chart Interactive

Activity rings for each day of the week, with a day picker and per-ring totals against goals.

Radial Chart Interactive 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.

A `Card` with a `ToggleGroup` of seven days, each showing small rings, above a large ring view and per-ring totals. The rings are drawn with `Svg` circles colored through `ChartPalette`; `RINGS` sets each label, unit, goal and color, and `WEEK` holds three values per day. Picking a day updates the large rings and the totals, which show the value, goal and percentage, with a note when a goal is met.

## Installation

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

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

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

The CLI also adds what it builds on: [Card](/docs/components/card), [Chart](/docs/components/chart), [Text](/docs/components/text), [Toggle Group](/docs/components/toggle-group).

4. Update the import paths to match your project.

**StyleSheet**

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), [Text](/docs/components/text), [Toggle Group](/docs/components/toggle-group).

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

```tsx title="stylesheet/components/charts/radial-chart-interactive.tsx"

1. Target iOS 17 or later.

2. Copy the theme files every view uses:

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

## Usage

```tsx
import { RadialChartInteractive } from "@/components/charts/radial-chart-interactive"
```

```tsx
<RadialChartInteractive />
```

Replace `WEEK` with your daily values and adjust the goals, units and colors in `RINGS`. The component takes no props.
