swift-charts
Build data visualizations with bar, line, area, point, pie, and donut charts in Swift.
- Compose marks (
BarMark,LineMark,PointMark,AreaMark,RuleMark,RectangleMark,SectorMark) inside aChartcontainer and configure axes, scales, and legends with view modifiers - Support for multi-series encoding via
.foregroundStyle(by:), symbol and line style variations, and stacked or grouped layouts - Selection, scrolling, and annotation capabilities (iOS 17+); vectorized plots (
BarPlot,LinePlot,AreaPlot,PointPlot) for datasets exceeding 1000 points (iOS 18+) - Specialized patterns for heat maps, Gantt charts, sparklines, threshold lines, and function plotting with explicit domain control
- Comprehensive review checklist and common-mistake guidance covering data model setup, accessibility, Dynamic Type compatibility, and performance optimization
Swift Charts
Build data visualizations with Swift Charts targeting iOS 26+. Compose marks
inside a Chart container, configure axes and scales with view modifiers, and
use vectorized plots for large datasets.
See references/charts-patterns.md for extended patterns, accessibility, and theming guidance.
