Swift chartsで棒グラフのx軸を時系列に表示させたい。

Question

Swiftのグラフを作成するchartsライブラリでX軸に曜日、Y軸に歩数を表示する棒グラフを作成しました。X軸はIAxisValueFormatter を使ってSunからSatまで表示させる([Sun,Mon,Tue,Wed,Thu,Fri,Sat])ことができたのですが、例えば今日が水曜日なら[Thu,Fri,Sat,Sun,Mon,Tue,Wed]の順番に表示させたいのですが、やり方が分からず困っております。どなたかご教示いただけると大変助かります。
開発環境：Xcode version 12.5 MacOS Big Sur version 11.2.3

ソースコード：

class XAxisValueFormatter: NSObject, IAxisValueFormatter {

let week = ["Sun","Mon","Tue","Wed","Thu","Fri","Sat"]

func stringForValue(_ value: Double, axis: AxisBase?) -> String {
    
    return week[Int(value)]

  }

}

func setUpBarChart(values:[Step]){
    
    self.barChartView.frame = CGRect(x: 20, y: 450, width: self.view.frame.width - 40, height: (self.view.frame.width - 40)/2)
    
    barChartView.backgroundColor = .clear
    barChartView.xAxis.labelPosition = .bottom
    barChartView.xAxis.labelTextColor = .systemBlue
    barChartView.xAxis.drawGridLinesEnabled = false
    barChartView.xAxis.drawAxisLineEnabled = false
    barChartView.xAxis.labelCount = 7
    barChartView.xAxis.valueFormatter = XAxisValueFormatter()
    
    barChartView.rightAxis.enabled = false
    
    barChartView.leftAxis.enabled = true
    barChartView.leftAxis.labelTextColor = .systemBlue
    barChartView.leftAxis.drawAxisLineEnabled = false
    barChartView.legend.enabled = false
    barChartView.animate(xAxisDuration: 1)
    
    var entry = [BarChartDataEntry]()
    
    for i in 0..<values.count {
        
        let weekday = Calendar.current.component(.weekday, from: values[i].date)
        
        entry.append(BarChartDataEntry(x:Double(weekday-1), y:Double(values[i].count)))

        weeklyAverage += values[i].count
        
    }
    
    weeklyAverage = Int(weeklyAverage / 7)

    aveLine = ChartLimitLine(limit: Double(weeklyAverage))
    aveLine.lineColor = .systemBlue
    aveLine.lineDashLengths = [4]
    barChartView.leftAxis.addLimitLine(aveLine)
    weeklyAverage = 0
    
    let dataSet = BarChartDataSet(entries: entry, label:"")

    dataSet.valueTextColor = .blue
    barChartView.data = BarChartData(dataSet: dataSet)
    scrollView.addSubview(barChartView)

}
