swift / charts：图表值int而不是double

Question

我想将1.00和2.00变为1和2.当我尝试将entry.y = Double(value)更改为entry.y = Int(value)时，它说它必须是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)
        }

这是我使用的图表：

Answer 1

let pieChartView = PieChartView（frame：CGRect（x：60，y：50，width：200，height：300））

    let track = ["Passed", "Failed", "Pending"]
    let money = [10, 6, 10]

    var entries = [PieChartDataEntry]()
    for (index, value) in money.enumerated() {
        let entry = PieChartDataEntry()

        entry.y = Double(value)

       entry.label = track[index]
        entries.append( entry)
    }

let set = PieChartDataSet（values：entries，label：“”）

let data = PieChartData（dataSet：set）

pieChartView.data =数据

让formatter = NumberFormatter（）

formatter.minimumFractionDigits = 0

   data.setValueFormatter(DefaultValueFormatter(formatter:formatter))

Answer 2

代替：

entry.y = Double(value)

做：

entry.y = Int(value)

请注意，2.1，2.2等将返回2

Answer 3

试试这个：

let number = NSNumber(value: value)
entry.y = number.integerValue
