Question

I\'ve created a BarChart using BarChartView from ios-Charts but I can\'t figure out howto add rounded corners to bars.

This is the code that I\'m using:

Answer 1

In BarChartRenderer.swift you can to modify open func drawDataSet(context: CGContext, dataSet: IBarChartDataSet, index: Int)

Then there's if-statement for stacked and nonstacked bars, choose your case and remove:

context.fill(barRect)

and instead of it add:

let bezierPath = UIBezierPath(roundedRect: barRect, cornerRadius: %YOUR_CORNER_RADIUS%)
context.addPath(bezierPath.cgPath)

context.drawPath(using: .fill)
