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.
