Open Source Swift Charting Libraries

An elegant modern declarative data visualization chart framework for iOS, iPadOS and macOS. Extremely powerful, supports line, spline, area, areaspline, column, bar, pie, scatter, angular gauges, arearange, areasplinerange, columnrange, bubble, box plot, error bars, funnel, waterfall and polar chart types. AAInfographics is the Swift language version of AAChartKit which is object-oriented, a set of easy-to-use, extremely elegant graphics drawing controls,based on the popular open source front-end chart library Highcharts. It makes it very fast to add interactive charts to your mobile projects. It supports single touch-drag for data inspection, multi-touch for zooming, and advanced responsiveness for your apps. Unlike previous imperative programming techniques, drawing any custom chart in AAChartKit, you don't need to care about the inner implementation details which is annoying && boring. Describe what you want, you will get what you described.

Line and area chart library for iOS. The chart can be initialized from the Interface Builder. Drag a normal View into a View Controller and assign to it the Chart Custom Class from the Identity Inspector. As you can see, as default the values on the x-axis are the progressive indexes of the passed array. You can customize those values by passing an array of (x: Double, y: Double) tuples to the series initializer. Use the chart.xLabels property to make the x-axis showing more labels than those inferred from the actual data. To make the chart respond to touch events, implement the ChartDelegate protocol in your class, e.g. a View Controller, and then set the chart’s delegate property.
