ios - 如何删除 LineChartView iOS 图表中的点

Question

我在学习ios-charts .我正在使用找到的教程 here .第一张图片显示了我得到的结果。你如何去除蓝色圆点，使其只显示像第二张图片中所示的平滑线？

代码片段如下

import UIKit
import Charts

class ChartsViewController: UIViewController {

@IBOutlet weak var lineChartView: LineChartView!

override func viewDidLoad() {
    super.viewDidLoad()

    // Do any additional setup after loading the view.

    let months = ["Jan", "Feb", "Mar", "Apr", "May", "Jun"]
    let unitsSold = [20.0, 4.0, 6.0, 3.0, 12.0, 16.0]

    setChart(months, values: unitsSold)

}

func setChart(dataPoints: [String], values: [Double]) {

    var dataEntries: [ChartDataEntry] = []

    for i in 0..<dataPoints.count {
        let dataEntry = ChartDataEntry(value: values[i], xIndex: i)
        dataEntries.append(dataEntry)
    }

    let lineChartDataSet = LineChartDataSet(yVals: dataEntries, label: "Units Sold")
    let lineChartData = LineChartData(xVals: dataPoints, dataSet: lineChartDataSet)
    lineChartView.data = lineChartData

}

}

将 .setDrawCircles = NO; 的 LineDataSet 设置为禁用圆的绘制。
