[mdm84]

Added the barCornerRadiusFactor property in Dataset for barchat. If you set the value different from 0.0 the bars will have the round corners

#4968

Goals ⚽

Get the chance for drawing the corner in the bar when you use the Bar Chart

Implementation Details 🚧

Create a property called barCornerRadiusFactor. We can set the factor for barWidth and create the appropriate corner in the bar

Testing Details 🔍

for testing, you can set the value in the demo project and see the behavior

no offence, have you checked out #4339 ? There was some legacy discussion that not seeing a perfect solution - mainly when then bar is thin, the rounded corner is more like an oval - making it not favorable merging into master

@liuxuan30 any news?

Thanks this work, but it rounded all corners. I change code with rounded top use pmairoldi code but change -
let bezierPath = UIBezierPath(roundedRect: barRect, cornerRadius: barRect.width * dataSet.barCornerRadiusFactor)
to this code -
let bezierPath = UIBezierPath(roundedRect: barRect, byRoundingCorners: [.topLeft , .topRight], cornerRadii: CGSize(width: barRect.width * dataSet.barCornerRadiusFactor, height: barRect.height * dataSet.barCornerRadiusFactor))
change cornerRadii parameters for your settings if need

yes, this should be an option (choose the corner to rounding and by default .all)

Is this already available in Release 5.0.0? Would really need the rounded corner support for bar charts

I write how do it. Please dive into the code to understand how it works.
