SwiftUI-Data-Visualization

Statistical, financial and live charts for SwiftUI on iOS and macOS, built on Swift Charts.

7StarsLatest Release: v2.0.1Updated: October 15, 2026
Platforms:iOS 17macOS 14

License: MIT

A dependency-free Swift package with ten chart views — time series, histogram, box plot, scatter with trend line, candlestick, waterfall, heatmap, radar, treemap and live ticker — and the public analysis types behind them: Histogram, BoxPlotSummary, LinearRegression, MovingAverage, NiceScale, TreemapLayout and Largest-Triangle-Three-Buckets downsampling. Inputs that are not finite are left out and extreme values are drawn at a documented limit, and the test suite renders every chart with these extreme inputs.

Features

  • TimeSeriesChart downsamples each series to 1,000 points with LTTB, draws moving averages, scrolls through a visible time window and reports the selected date
  • Statistics charts: HistogramChart (Sturges, Freedman–Diaconis, fixed width or count), BoxPlotChart with Tukey whiskers, ScatterChart with a least-squares trend line
  • Finance charts: CandlestickChart with Candle.aggregate(_:interval:) and WaterfallChart with totals
  • HeatmapChart, RadarChart and a squarified TreemapChart; radar and ticker draw with Canvas, treemap with plain SwiftUI views; all three attach an AudioGraphDescriptor for VoiceOver
  • Live data with RingBuffer and the observable LiveSeries feeding LiveTickerChart
  • The analysis is public and Sendable, so it can be used in a Chart of your own or off the main actor
  • Palettes set through .chartPalette(_:), including a color-blind safe palette; ChartExport renders a chart to PNG data or a CGImage
  • A test suite that feeds nan, infinity, Int.max, extreme ranges and extreme dates to the analysis types and renders every chart with them

7        values: [4_200, 8_100, 6_900, 10_400, 7_800, 12_100, 9_300],
8        start: .now.addingTimeInterval(-6 * 86_400),

Timeline

  1. Repository opened with bar, pie, scatter and candlestick views

  2. Version 1.0.0 released; its sources did not build with current Xcode versions

  3. Legacy modules removed and the package reduced to a small placeholder

  4. Rebuilt on Swift Charts as 2.0.0, bringing in the tested algorithms and charts of SwiftUI-Charts-Pro, which was archived

  5. 2.0.1: extreme finite values clamped before Swift Charts, every same-date candle drawn
