ios - 从 iOS 图表饼图中删除值标签

问题描述

我有一个饼图，我试图从图表中删除值标签，因为它们相互溢出，但似乎没有代码将其删除。

这是我一直用来尝试删除它的代码：

chartIMG.drawEntryLabelsEnabled = false

但它似乎不起作用。

我创建图表的代码：

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

    var dataEntries: [ChartDataEntry] = []

    for i in 0..<dataPoints.count {
        let dataEntry1 = PieChartDataEntry(value: Double(i), label: dataPoints[i], data:  dataPoints[i] as AnyObject)

        dataEntries.append(dataEntry1)
    }
    print(dataEntries[0].data)
    let pieChartDataSet = PieChartDataSet(values: dataEntries, label: "Symptoms")
    let pieChartData = PieChartData(dataSet: pieChartDataSet)
    chartIMG.data = pieChartData
    chartIMG.drawEntryLabelsEnabled = false
    chartIMG.chartDescription?.text = ""
    var colors: [UIColor] = []

    for _ in 0..<dataPoints.count {
        let red = Double(arc4random_uniform(256))
        let green = Double(arc4random_uniform(256))
        let blue = Double(arc4random_uniform(256))

        let color = UIColor(red: CGFloat(red/255), green: CGFloat(green/255), blue: CGFloat(blue/255), alpha: 1)
        colors.append(color)
    }


    pieChartDataSet.colors = colors
}

这是删除它的唯一方法还是我做错了什么？

解决方案

如果您需要禁用数据集条目的绘图值，请使用此

pieChartDataSet.drawValuesEnabled = false

如果您需要禁用某些轴上的绘图值，请使用：

chartIMG.rightAxis.drawLabelsEnabled = false
chartIMG.leftAxis.drawLabelsEnabled = false
chartIMG.xAxis.drawLabelsEnabled = false
chartIMG.rightAxis.drawLabelsEnabled = false
