我想把 1.00 和 2.00 变成 1 和 2。当我试图改变它时entry.y = Double(value)，entry.y = Int(value)它说它必须是一个 Double。如何将值转换为整数？

var entries = [PieChartDataEntry]()
        for (index, value) in dataarray.enumerated() {
            let entry = PieChartDataEntry()
            entry.y = Double(value)
            entry.label = self.labels[index]
            entries.append(entry)
        }

这是我正在使用的图表：

我使用的是Charts框架(Daniel gindi).它运行正常,但如何在饼图上显示%(符号)？
我也尝试使用NSNumberFormatter()方法获取percantage中的隐蔽数据值但不获取%符号.
我在这里上传代码

    override func viewDidLoad() {
            super.viewDidLoad()
            var data = [25.0,37.5,12.5,12.5,12.5] // pie chart data 
            var status = ["A","B","C","D","E"] // status
            setChart(status, values: data)
            self.pieChart.drawSliceTextEnabled = false

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

            pieChart.noDataText = "you need to provide data for chart"
            pieChart.noDataTextDescription = ""
            self.pieChart.descriptionText = ""

            var dataEntries: [ChartDataEntry] = []
            //pieChart.centerText = " "
            for i in 0..<dataPoints.count {

                let dataEntry = ChartDataEntry(value: values[i], xIndex: i)
                dataEntries.append(dataEntry)

            }
