Using PGLevelIndicator

• Create attributed strings with the text you want

let font: UIFont? = UIFont(name: "Avenir-Book", size: 18)
let fontSuper: UIFont? = UIFont(name: "Avenir-Book", size: 10)

let attStringNO2 = NSMutableAttributedString(string: "NO2", attributes: [.font: font!])

attStringNO2.setAttributes([.font: fontSuper!, .baselineOffset: -5],
                          range: NSRange(location: 2, length: 1))

• Create an array of parameters:

let parameters = [ItemParameters(title: attStringNO2, titleColor: UIColor.red, level: .low),
                  ItemParameters(title: attStringO3, titleColor: UIColor.yellow, level: .medium),
                  ItemParameters(title: attStringpM10, titleColor: UIColor.green, level: .high),
                  ItemParameters(title: attStringPM25, titleColor: UIColor.orange, level: .low)]

(The level parameter is not used, but maybe in future revisions we will use it)

• Create the PGLevelIndicator object:

let levelIndicator = PGLevelIndicator(frame: CGRect(x: 0,
                                                    y: 100,
                                                    width: self.view.frame.size.width,
                                                    height: self.view.frame.size.width),
                                      itemsParameters: parameters)

• And finally, add the levelIndicator to the main view

self.view.addSubview(levelIndicator!)

And voilá....
