Percentage is not show on pie chart

Hi there,

Although although my last Charts version shown percentage, current Charts version didn't show. How can I fix it.

My code:

let pFormatter = NumberFormatter()
pFormatter.numberStyle = .percent
pFormatter.maximumFractionDigits = 1
pFormatter.multiplier = 1
pFormatter.percentSymbol = " %"
data.setValueFormatter(DefaultValueFormatter(formatter: pFormatter))

Start by reproducing the pie-chart behavior with the provided NumberFormatter and DefaultValueFormatter code in Charts. Compare the current version's output with the reported previous-version behavior; done means the pie chart displays percentage labels as expected.
