Set line cap to CGMutablePath

[Lukaz32]

Hi,
I'm trying to achieve an effect like that to my pie chart:

( I mean the rounded edges)

I've tried to add context.setLineCap(.round) to the PieChartRenderer but it makes no difference.

Does anyone know how I can achieve that?

Thanks.

I did a quick check, the pie chart is not simply an arc with rounded cap. It may contains two arc and draw the lines to connect them.

You might need to replace addLine() with arcs as the rounded effect in open func drawDataSet(context: CGContext, dataSet: IPieChartDataSet). You have to calculate your arc though.

I stroke the path so you know the edges:

@Lukaz32 - Do you have any snippets of code you wouldn't mind sharing that you used to make this happen?
