How to access the Position of labels on x axis of Combined Line and Bar chart on swift(3.0.1)

[goel232]

I have done the same thing in swift2 like this

       func setChart(_ xValues: [String], yValuesLineChart: [Double], yValuesBarChart: [Double] ,         combinedChartView:CombinedChartView) {        
          
      combinedChartView.noDataText = "Please provide data for the chart."
          var yVals1 : [ChartDataEntry] = [ChartDataEntry]()
          var yVals2 : [BarChartDataEntry] = [BarChartDataEntry]()  
      for i in 0..<xValues.count {
            
          yVals1.append(ChartDataEntry(value: yValuesLineChart[i], xIndex: i))
          yVals2.append(BarChartDataEntry(value: yValuesBarChart[i] , xIndex: i))
            
        }
    let lineChartSet = LineChartDataSet(yVals: yVals1, label: "Line Data")
    let barChartSet: BarChartDataSet = BarChartDataSet(yVals: yVals2, label: "Bar Data")

    let data: CombinedChartData = CombinedChartData(xVals: xValues)
    data.barData = BarChartData(xVals: xValues, dataSets: [barChartSet])
    if yValuesLineChart.contains(0) == false {
    data.lineData = LineChartData(xVals: xValues, dataSets: [lineChartSet])
    }
    combinedChartView.data = data
}

found the answer

     func setChart(_ xValues: [String], yValuesLineChart: [Double], yValuesBarChart: [Double] , combinedChartView:CombinedChartView) {
        combinedChartView.noDataText = "Please provide data for the chart."
    
    var yVals1 : [ChartDataEntry] = [ChartDataEntry]()
    var yVals2 : [BarChartDataEntry] = [BarChartDataEntry]()
    for i in 0..<xValues.count {
        yVals1.append(ChartDataEntry(x: Double(i), y: yValuesLineChart[i],data: xValues as AnyObject?))
        yVals2.append(BarChartDataEntry(x: Double(i), y: yValuesBarChart[i],data: xValues as AnyObject?))
    }
        let lineChartSet = LineChartDataSet(values: yVals1, label: "Line Data")
        let barChartSet: BarChartDataSet = BarChartDataSet(values: yVals2, label: "Bar Data")
        let data: CombinedChartData = CombinedChartData()
        data.barData=BarChartData(dataSets: [barChartSet])
        if yValuesLineChart.contains(0) == false {
            data.lineData = LineChartData(dataSets:[lineChartSet] )
            
        }
        **combinedChartView.data = data
        combinedChartView.xAxis.valueFormatter = IndexAxisValueFormatter(values:xValues)
        combinedChartView.xAxis.granularity = 1**
        }
