Easing animation for highlighting in Pie Chart #3482

Open azri92 opened 6 years ago

azri92 commented 6 years ago

Currently, the default highlighting pops in and out without any easing - making it look jumpy. Is there a way to add some easing to the highlight?

You can achieve this effect by animating the PieDataSet selectionShift property itself. Run this in the onValueSelected of the chartValueSelectedListener of your PieChart:

ValueAnimator.ofFloat(0f, 1f).apply { duration = 200 addUpdateListener { pieDataSet.selectionShift = it * 8f pieChartView.invalidate() } start() }
