iOS pie chart properties

Question

I´m using Charts for iOS and have a pie chart. I would like to remove the inner circle and change the width for each pie inside the pie chart. I have not been able to find how to decrease the width for the pie chart and remove the inner circle.

The image is what I want to do.

I have tried on my PieChartView to change the draw properties but have not succeeded. Any ideas how to solve this?

How to give border to each slice in this library ? – NavinBagul Aug 28 '19 at 10:51 — NavinBagul, Aug 28 '19 at 10:51

PieChartView has the following properties:

holeRadiusPercent
transparentCircleRadiusPercent

Set them both to 0.0 and you should achieve what you want.

You can also hide the hole explicitly by setting chartView.drawHoleEnabled = false

If you need more properties, just open the source code. It is heavily commented.

Adding to @sulthan's response with some example code.

The CGSize of the chart view's frame can be modified to affect the chart width itself.

However, a CGSize which exceeds the CGSize of the chart's parent view may result in unpredictable layouts.

let chart = PieChartView( frame: self.view.frame)
// setup data...etc.

// style
chart.holeRadiusPercent = 0
chart.transparentCircleColor = UIColor.clear

// increase width
// width in excess of the parentView.size.width will cause layout issues
chart.frame.size = CGSize(width: 500, height: chart.frame.size.height)
