Easy to use Spider (Radar) Chart library for iOS written in Swift

pod "DDSpiderChart"

let spiderChartView = DDSpiderChartView(frame: .zero) // Replace with some frame or add constraints
spiderChartView.axes = ["Axis 1", "Axis 2", "Axis 3", "Axis 4"] // Set axes by giving their labels
spiderChartView.addDataSet(values: [1.0, 0.5, 0.75, 0.6], color: .red) // Add first data set
spiderChartView.addDataSet(values: [0.9, 0.7, 0.75, 0.7], color: .blue) // Add second data set

let dataSet1 = spiderChartView.addDataSet(values: [0.9, 0.7, 0.75, 0.7], color: .blue) // Add second data set
// Later
spiderChartView.removeDataSetView(dataSet!)

spiderChartView.color = .white // This will change the color of the circles
spiderChartView.circleCount = 20 // How many circles there will be
spiderChartView.circleGap = 5 // The distance between circles
// circleCount * circleGap would be the radius of the chart itself

// Custom font with custom size & color example
func attributedAxisLabel(_ label: String) -> NSAttributedString {
  let attributedString = NSMutableAttributedString()
  attributedString.append(NSAttributedString(string: label, attributes: [NSForegroundColorAttributeName: UIColor.black, NSFontAttributeName: UIFont(name: "AvenirNextCondensed-Bold", size: 16)!]))
  return attributedString
