Linear chart using UIBezierPath

Implementation

If you inlcudes the file LinearChart.swift you're able to import ad UIView to your project and change the class to LinearChart. And now the UIView is able to recive the datasource and render it in real time, using: linearChartView.dataset = dataset

Example

class ViewController: UIViewController {

    @IBOutlet weak var linearChartView: LinearChart!
    var dataset:[LinearChartModel] = [LinearChartModel]()
    
    override func viewDidLoad() {
        super.viewDidLoad()
        
        let dato1:LinearChartModel=LinearChartModel()
        dato1.x = 10
        dato1.y = (linearChartView.frame.height - 100)
        dataset.append(dato1)
        
        let dato2:LinearChartModel=LinearChartModel()
        dato2.x = 100
        dato2.y = (linearChartView.frame.height - 30)
        dataset.append(dato2)
        
        let dato3:LinearChartModel=LinearChartModel()
        dato3.x = 200
        dato3.y = (linearChartView.frame.height - 240)
        dataset.append(dato3)
        
        let dato4:LinearChartModel=LinearChartModel()
        dato4.x = 330
        dato4.y = (linearChartView.frame.height - 10)
        dataset.append(dato4)
        
        linearChartView.dataset = dataset
        // Do any additional setup after loading the view, typically from a nib.
    }
    
    
    @IBAction func reload(_ sender: Any) {
        dataset.removeAll()
        let dato1:LinearChartModel=LinearChartModel()
        dato1.x = 30
        dato1.y = (linearChartView.frame.height - 70)
        dataset.append(dato1)
        
        let dato2:LinearChartModel=LinearChartModel()
        dato2.x = 130
        dato2.y = (linearChartView.frame.height - 230)
        dataset.append(dato2)
        
        let dato3:LinearChartModel=LinearChartModel()
        dato3.x = 180
        dato3.y = (linearChartView.frame.height - 20)
        dataset.append(dato3)
        
        let dato4:LinearChartModel=LinearChartModel()
        dato4.x = 320
        dato4.y = (linearChartView.frame.height - 150)
        dataset.append(dato4)
        
        linearChartView.dataset = dataset
    }
    
    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }


}
