Animation on PieChartView

[manan19]

How do I animate the transparentCircleRadiusPercent and holeRadiusPercent properties on a PieChartView?

I tried this but it doesn't work

UIView.animate(withDuration: 0.6, animations: {
            self.pieChartView.holeRadiusPercent = 1
            self.pieChartView.transparentCircleRadiusPercent = 1
        }) { (finished) in
            self.pieChartView.data = PieChartData(dataSet: dataSet)
            UIView.animate(withDuration: 0.5, animations: {
                self.pieChartView.holeRadiusPercent = 0.9
                self.pieChartView.transparentCircleRadiusPercent = 0.9
            }, completion: { (finished) in

            })
        }

It's not the same as UIView animation, as this library is based on CoreGraphics. Seems you have to write yourself (a display link maybe). Take a look at Animator.swift.
