chartTranslated in a Pie Chart is not called

What did you do?

I have created a simples Pie Chart, but chartTranslated is never called even thou the other ChartViewDelegate methods are working fine.

I have set pieChartView's delegate in the viewDidLoad of ViewController

override func viewDidLoad() {
    super.viewDidLoad()
    pieChartView.delegate = self
}

//...

func chartTranslated(_ chartView: ChartViewBase, dX: CGFloat, dY: CGFloat) {
    print("Point (\(dX), \(dY))")
}

What did you expect to happen?

I was expecting chartTranslated to be called whenever I drag the Pie chart and print every point variation in console.

What happened instead?

Nothing happens! chartTranslated method is not called and the print("") I have put inside it doesn't print anything.

chartTranslated is never called in pie chart. I'm not sure why, but if you want it, you can override some methods and add it in your sub pie chart class.

Any tips on how to get chartTranslated called from a piechart? How would I override 'some methods'?
