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.

Usage

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

<RadialChartRings />

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