PieChart percent values are always rounded up to integer, I would like to show them as float.

Hi there,

I am using a piechart but having problems with labels of each slice. What I want to achieve is this:
My goal

And this is what I have so far:
My progress

So here are my questions:

1. How to show labels as Float instead of Int? [SOLVED]
2. How to show the percent signs near the labels? [SOLVED]
3. How to hide labels for small slices?

These are my settings so far:

            piechart.highlightPerTapEnabled = false

            piechart.rotationEnabled = false

            piechart.usePercentValuesEnabled = true

            piechart.drawSliceTextEnabled =  false

            piechart.drawHoleEnabled = false

Solved 1 and 2 by using:

            let formatter = NSNumberFormatter()
            formatter.numberStyle = .PercentStyle
            formatter.maximumFractionDigits = 1
            formatter.multiplier = 1.0
            data.setValueFormatter(formatter)

Still need a way to disable labels for slices under X% percent of pie.

last one is dup I guess, closing. check #944

let formatter = NSNumberFormatter()
formatter.numberStyle = .PercentStyle
formatter.maximumFractionDigits = 1
formatter.multiplier = 1.0
data.setValueFormatter(formatter)

It is still a valid solution ? Me did not work.
