Cartes ios Les étiquettes xaxis ne sont pas alignées

Question

J'ai créé un diagramme à barres groupé avec des valeurs assez simples. J'ai 5 étiquettes que je voudrais étaler le long des groupes xaxis et 3 barres pour coïncider avec chaque étiquette de xaxis.

Le graphique affiche maintenant 1 étiquette xaxis et 1 barre. (ils peuvent être hors cadre, c'est difficile à dire.) J'ai besoin de chaque cas à synchroniser avec le bon label msArrayAxis.

Voici le code:

var msArrayXAxis = ["0-20", "20-50", "50-100", "100-200", "<200"] 


barchartView.isUserInteractionEnabled = false 
    barchartView.noDataText = "You need to provide data for the chart." 
    barchartView.legend.enabled = false 
    barchartView.chartDescription?.text = "" 

    barchartView.xAxis.labelPosition = XAxis.LabelPosition.bottom 
    barchartView.xAxis.valueFormatter = IndexAxisValueFormatter(values: msArrayXAxis) 

    barchartView.xAxis.axisMinimum = 0 

    barchartView.xAxis.granularity = 2 
    barchartView.xAxis.setLabelCount(5, force: true) 

    barchartView.xAxis.spaceMin = 0.3 
    //  barchartView.extraBottomOffset = 1 
    barchartView.xAxis.labelWidth = 1 
    barchartView.xAxis.avoidFirstLastClippingEnabled = true 
    barchartView.rightAxis.drawGridLinesEnabled = false 
    barchartView.rightAxis.drawAxisLineEnabled = false 
    barchartView.rightAxis.drawLabelsEnabled = false 

func parsedArrayCount(case1: Array<Double>,case2: Array<Double>,case3: Array<Double>,case4: Array<Double>, case5: Array<Double>) -> [BarChartDataEntry] { 

    var dataEntries1: [BarChartDataEntry] = [] 

    NSLog("Parsing array count") 

    let dataEntry = BarChartDataEntry(x: Double(0), y:Double(case1.count)) 
    dataEntries1.append(dataEntry) 

    let dataEntry2 = BarChartDataEntry(x: Double(1), y:Double(case2.count)) 
    dataEntries1.append(dataEntry2) 

    let dataEntry3 = BarChartDataEntry(x: Double(2), y:Double(case3.count)) 
    dataEntries1.append(dataEntry3) 

    let dataEntry4 = BarChartDataEntry(x: Double(3), y:Double(case4.count)) 
    dataEntries1.append(dataEntry4) 

    let dataEntry5 = BarChartDataEntry(x: Double(1), y:Double(case5.count)) 
    dataEntries1.append(dataEntry5) 

    return dataEntries1 
}

    barchartView.clear()

    if array != nil && array!.count > 0 { 

     for i in 0..<array!.count { 
      rArray.append(array![i].r) 
      nameArray.append(array![i].name) 
     }
