Проблема при создании гистограмм с правильными полями слева и справа

/ 28 октября 2019

Я пытаюсь создать комбинированный график, используя danielgindi / Charts .

Но когда я создаю гистограммы, я не могу добавить правильные поля с левой и правой стороны графика, и поэтому он обрезается с обеих сторон.

enter image description here

Это то, что я получаю. На графике значения оси X не выровнены по графику, а левая и правая части обрезаются. Мне нужно правильно высветить X ZXIS и добавить поля слева и справа.

Код, который я использую, выглядит следующим образом 

override func viewDidLoad() {
    super.viewDidLoad()
    thirdHolderView.delegate = self
    thirdHolderView.chartDescription?.enabled = false
    thirdHolderView.drawBarShadowEnabled = false
    thirdHolderView.highlightFullBarEnabled = false
    thirdHolderView.drawOrder = [DrawOrder.line.rawValue, DrawOrder.bar.rawValue]

    let legendObj = thirdHolderView.legend
    legendObj.wordWrapEnabled = false
    legendObj.horizontalAlignment = .center
    legendObj.verticalAlignment = .bottom
    legendObj.orientation = .horizontal
    legendObj.drawInside = false


    //Right Y axis
    let rightAxis = thirdHolderView.rightAxis
    rightAxis.resetCustomAxisMin() //By calling this method, any custom minimum value that has been previously set is reseted, and the calculation is done automatically.
    rightAxis.resetCustomAxisMax() //By calling this method, any custom maximum value that has been previously set is reseted, and the calculation is done automatically.



    //Left Y axis
    let leftAxis = thirdHolderView.leftAxis
    leftAxis.resetCustomAxisMin() //By calling this method, any custom minimum value that has been previously set is reseted, and the calculation is done automatically.
    leftAxis.resetCustomAxisMax() //By calling this method, any custom maximum value that has been previously set is reseted, and the calculation is done automatically.


    let xAxis = thirdHolderView.xAxis
    xAxis.labelPosition = .bottom
    xAxis.resetCustomAxisMax() //By calling this method, any custom maximum value that has been previously set is reseted, and the calculation is done automatically.
    xAxis.resetCustomAxisMin() //By calling this method, any custom minimum value that has been previously set is reseted, and the calculation is done automatically.
    xAxis.granularity = 1.0
    xAxis.labelRotationAngle = 315.0
    xAxis.centerAxisLabelsEnabled = true
    xAxis.valueFormatter = self
    self.updateChartData()
}

override func updateChartData() {
    if self.shouldHideData {
        thirdHolderView.data = nil
        return
    }

    self.setChartData()
}

func setChartData() {
    let dataChartsMaster = CombinedChartData()
    dataChartsMaster.barData = generateBarData()
    thirdHolderView.doubleTapToZoomEnabled = false
    thirdHolderView.pinchZoomEnabled = true
    thirdHolderView.data = dataChartsMaster
}

func generateBarData() -> BarChartData {

    var salesEntries    : [BarChartDataEntry] = []
    var marginEntries   : [BarChartDataEntry] = []

    for i in 0..<yearsXAxis.count
    {
        let barEntry1 = BarChartDataEntry(x: (Double(yearsXAxis[i])!), y: Double(unitsSoldJ[i]))
        salesEntries.append(barEntry1)

        let barEntry2 = BarChartDataEntry(x: (Double(yearsXAxis[i])!), y: Double(unitsBoughtJ[i]))
        marginEntries.append(barEntry2)
    }

    //Barchart 1
    let chartDataSet1 = BarChartDataSet(entries: salesEntries, label: "Sales")
    chartDataSet1.setColor(UIColor(red: 60/255, green: 220/255, blue: 78/255, alpha: 1))
    chartDataSet1.valueTextColor = UIColor(red: 60/255, green: 220/255, blue: 78/255, alpha: 1)

    //Barchart 2

    let chartDataSet2 = BarChartDataSet(entries: marginEntries, label: "Margin")
    chartDataSet2.setColor(UIColor(red: 255/255, green: 0/255, blue: 0/255, alpha: 1))
    chartDataSet2.valueTextColor = UIColor(red: 60/255, green: 220/255, blue: 78/255, alpha: 1)


    let groupSpace = 0.1
    let barSpace = 1.05
    let barWidth = 0.25


    let data = BarChartData(dataSets: [chartDataSet1, chartDataSet2])
    data.barWidth = barWidth;
    data.groupWidth(groupSpace: groupSpace, barSpace: barSpace)

    return data
}

Может ли кто-нибудь помочь мне понять, где я нахожусьидет не так?

Заранее спасибо.
