Add percent label for pie chart

[stevedubz]

I have a pie chart and it displays the correct percents per item. The only problem is that it only displays a number like "55.0" and not "55.0%". I noticed you did this in one of your screenshots for the pie chart but I can't figure out how.

Add where ever you want to add the percent to.
pFormatter.percentSymbol = @" %";

  lazy var formatter:NSNumberFormatter = {
        let a = NSNumberFormatter()
        a.numberStyle = .PercentStyle
        a.maximumFractionDigits = 0
        a.multiplier = 1
        a.percentSymbol = " %"
        return a
    }()

After that
pieChatView.data?.setValueFormatter(formatter)

For: pieChatView.data?.setValueFormatter(formatter)

Cannot convert value of type NumberFormatter to expected argument type IValueFormatter

@SylarRuby
let myFormatter = DefaultValueFormatter(formatter: formatter)
pieChatView.data?.setValueFormatter(myFormatter)
