Area Chart Range
A heart-rate card with a shaded low-to-high band and an average line across 24 hours.
Area Chart Range 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.

import com.esuiss.ui.components.CardVariantA ComposedChart that pairs a range Area, filled between each hour's low and high reading, with a Line for the hourly average. The header shows the day's lowest and highest values in BPM, and the tooltip formats both the range and the average with a custom row built from Text.

Usage
import { AreaChartRange } from "@/components/charts/area-chart-range"<AreaChartRange />Replace the readings array with [low, high, average] tuples for each hour; the header range and the chart data are derived from it. Adjust the YAxis domain and ticks to fit your values. The component takes no props.
