How to set BarChartView Stacked position to horizontal?

I have one requirement for one my app. I have to display the bar chart.

For each x -> Multiple y entires. Bars should not be stacked on top of each bar. I want to show the bars side by side for each x entries.

```
extension ViewController {

private func configureChart() {

// barChartView.delegate
barChartView.noDataText = "You need to provide data for the chart."
barChartView.chartDescription?.text = "sales vs bought "

//legend
let legend = barChartView.legend
legend.enabled = true
legend.horizontalAlignment = .right
legend.verticalAlignment = .top
legend.orientation = .vertical
legend.drawInside = true
legend.yOffset = 10.0;
legend.xOffset = 10.0;
legend.yEntrySpace = 0.0;

let xaxis = barChartView.xAxis
// xaxis.valueFormatter = axisFormatDelegate
xaxis.drawGridLinesEnabled = false
xaxis.labelPosition = .bottom
xaxis.centerAxisLabelsEnabled = true
xaxis.valueFormatter = IndexAxisValueFormatter(values:self.months)
xaxis.granularity = 1

let leftAxisFormatter = NumberFormatter()
leftAxisFormatter.maximumFractionDigits = 1

let yaxis = barChartView.leftAxis
yaxis.spaceTop = 0.35
yaxis.axisMinimum = 0
yaxis.drawGridLinesEnabled = false

barChartView.rightAxis.enabled = false
//axisFormatDelegate = self

setChart()
}

func setChart() {
barChartView.noDataText = "You need to provide data for the chart."
let dataEntries: [BarChartDataEntry] = [BarChartDataEntry(x: 0, yValues: self.unitsSold)]
let dataEntries1: [BarChartDataEntry] = [BarChartDataEntry(x: 0, yValues: self.unitsBought)]

let chartDataSet = BarChartDataSet(entries: dataEntries, label: "Unit sold")
let chartDataSet1 = BarChartDataSet(entries: dataEntries1, label: "Unit Bought")

let dataSets: [BarChartDataSet] = [chartDataSet, chartDataSet1]
chartDataSet.colors = [UIColor(red: 230/255, green: 126/255, blue: 34/255, alpha: 1)]
let chartData = BarChartData(dataSets: dataSets)
let barWidth = 0.3
chartData.barWidth = barWidth;
barChartView.notifyDataSetChanged()

barChartView.data = chartData
barChartView.backgroundColor = UIColor(red: 189/255, green: 195/255, blue: 199/255, alpha: 1)

//chart animation
barChartView.animate(xAxisDuration: 1.5, yAxisDuration: 1.5, easingOption: .linear)

}
}
```
Output:

Expected Output:

How to do this?

Review the configureChart and setChart snippets, focusing on BarChartDataSet, BarChartData, the x values, and barWidth. Done means the Unit sold and Unit Bought datasets render side by side for each x entry, matching the expected output rather than stacking.
