How to display second y-axis to right of grouped bar chart data in iOS - ios

Question

I am developing one activity tracker iOS application in which I need to show a history of steps and calories in a bar chart. I used iOS Charts
for this. I am able to get the grouped charts by using this but i am not able to show two seperate axis bars for steps and calories. Below is my requirment. Please suggest me how can i achive this using iOS-Charts or suggest me any other charts written in Swift.
Grouped Bar Chart
I wrote the code using iOS Charts library as below,
func setUpDataForCharts()
{
var weekDays = [String]()
for i in 1 ... 7
{
let value = String(i)
weekDays.append(value)
}
let steps = [2000, 4000, 3500, 1300, 5000, 4800, 2400]
let calories = [20.5, 40.3, 34.0, 13.3, 50.0, 80.2, 20.0]
setChartBarGroupDataSet(weekDays, values: steps, values2: calories)
//setChart(weekDays, values: steps)
barChartView.xAxis.labelPosition = ChartXAxis.LabelPosition.Bottom
barChartView.xAxis.drawGridLinesEnabled = false
}
func setChartBarGroupDataSet(dataPoints: [String], values: [Double], values2: [Double]) {
var dataEntries: [BarChartDataEntry] = []
var dataEntries2: [BarChartDataEntry] = []
for i in 0..<dataPoints.count {
let dataEntry = BarChartDataEntry(value: values[i], xIndex: i)
dataEntries.append(dataEntry)
}
for i in 0..<dataPoints.count {
let dataEntry = BarChartDataEntry(value: values2[i], xIndex: i)
dataEntries2.append(dataEntry)
}
let chartDataSet = BarChartDataSet(yVals: dataEntries, label: "Steps")
let chartDataSet2 = BarChartDataSet(yVals: dataEntries2, label: "Calories")
chartDataSet2.colors = [UIColor(hex: "3F7FD0")]
chartDataSet.colors = [UIColor(hex: "F53609")]
let dataSets: [BarChartDataSet] = [chartDataSet,chartDataSet2]
let data = BarChartData(xVals: dataPoints, dataSets: dataSets)
barChartView.data = data
barChartView.descriptionText = ""
barChartView.rightAxis.axisMaxValue = chartDataSet2.yMax + 1.0
barChartView.rightAxis.labelCount = chartDataSet2.valueCount
barChartView.rightAxis.drawGridLinesEnabled = true
barChartView.rightAxis.drawAxisLineEnabled = false
barChartView.rightAxis.drawLabelsEnabled = true
barChartView.animate(xAxisDuration: 2.0, yAxisDuration: 2.0, easingOption: .Linear)
}
Out put with the above code is,
Output
Thanks in advance!
