Ios iso图表圆角条形图

在条形图视图中是否有设置来启用条形图的圆角

我想达到与另一个库类似的效果

---

我制作了一系列ios图表来大致实现这一点：

---

这是一个在swift中使用UIView的圆形条形图示例。在.swift文件中，添加以下代码

@IBOutlet weak var barView: UIView! 
var BAR_WIDTH_CONSTANT: CGFloat = 9
var BAR_DISTANCE: CGFloat = 14 // distance between your bars
var BAR_MAX_HEIGHT: CGFloat = 50 // maximum height of a bar
let MAX_VALUE: CGFloat = 10 //maximum value of a bar
let MIN_VALUE: CGFloat = 0 // minimum value of a bar

然后在viewDidLoad（）中添加以下代码

var xPos:CGFloat=0
变量yPos:CGFloat=0
让值：[Int]=[1,2,3,4,5,6,7]//条形图的值
对于0中的i..CGFloat{
设barHeight=（maxHeight*height）/（maxValue-minValue）
返回杆高度
}

---

希望能有所帮助。

现在就开始测试吧。

@IBOutlet weak var barView: UIView! 
var BAR_WIDTH_CONSTANT: CGFloat = 9
var BAR_DISTANCE: CGFloat = 14 // distance between your bars
var BAR_MAX_HEIGHT: CGFloat = 50 // maximum height of a bar
let MAX_VALUE: CGFloat = 10 //maximum value of a bar
let MIN_VALUE: CGFloat = 0 // minimum value of a bar

 var xPos: CGFloat = 0
 var yPos: CGFloat = 0
 let values: [Int] = [1, 2, 3, 4, 5, 6, 7] //values of a Bar chart
 for i in 0..< values.count {
     // draw bar
     let barHeight = getBarHeight(height: CGFloat(values[i]), maxHeight: BAR_MAX_HEIGHT, maxValue: MAX_VALUE, minValue: MIN_VALUE)
     yPos = BAR_MAX_HEIGHT - barHeight
     let frame = CGRect(x: xPos, y: yPos, width: BAR_WIDTH_CONSTANT, height: barHeight)
     let bar = UIView(frame: frame)

     bar.layer.cornerRadius = BAR_WIDTH_CONSTANT < barHeight ? BAR_WIDTH_CONSTANT / 2 : barHeight / 2
     bar.layer.masksToBounds = true
     self.barView.addSubview(bar)

     xPos = xPos + BAR_WIDTH_CONSTANT + BAR_DISTANCE
     // bar drawing complete
}


func getBarHeight(height: CGFloat, maxHeight: CGFloat, maxValue: CGFloat, minValue: CGFloat) -> CGFloat {
        let barHeight = (maxHeight * height ) / (maxValue - minValue)
        return barHeight
}
