How do I render bar charts by DateTime?

[sun_caramel]

How can I set the x-axis of a QBarSeries to QDateTimeAxis?
I want to render the candlestick chart and the bar chart into one chart

below code is my sample code, I will convert from python to C++

from PyQt5.QtChart import (
    QBarCategoryAxis,
    QBarSeries,
    QBarSet,
    QCandlestickSeries,
    QCandlestickSet,
    QChart,
    QChartView,
    QDateTimeAxis,
    QScatterSeries,
    QValueAxis,
)
from PyQt5.QtCore import QDateTime
from PyQt5.QtGui import QPainter
from PyQt5.QtWidgets import QApplication, QLabel, QMainWindow, QVBoxLayout, QWidget

app = QApplication([])


class win(QMainWindow):
    widget: QWidget = QWidget()
    layout: QVBoxLayout = QVBoxLayout()
    chartView: QChartView = QChartView()
    chart: QChart = QChart()
    label: QLabel = QLabel()
    scatter: QScatterSeries

    def __init__(self):
        super().__init__()
        self.setMinimumSize(600, 400)

        min = 1704157200 * 1000
        max = 1704160800 * 1000
        cur = 1704157800 * 1000
        minY = 49000
        maxY = 56000
        raw_data = [
            (min, 45000),
            (max, 58000),
        ]

        series = QCandlestickSeries()
        data = QCandlestickSet()
        data.setTimestamp(cur)
        data.setOpen(55000)
        data.setHigh(53000)
        data.setLow(54000)
        data.setClose(52000)
        series.append(data)

        # chart object
        chart = QChart()
        # chart.legend().hide()

        trade = QCandlestickSeries()
        tradeSet = QCandlestickSet()
        price = 50000
        tradeSet.setOpen(price)
        tradeSet.setClose(price)
        tradeSet.setHigh(price)
        tradeSet.setLow(price)
        tradeSet.setTimestamp(cur)
        trade.append(tradeSet)

        chart.addSeries(series)
        chart.addSeries(trade)

        test = QScatterSeries()
        test.append(cur, 49000)

        chart.addSeries(test)

        # bar chart

        bars = QBarSeries()
        curTime = QDateTime.fromMSecsSinceEpoch(cur)
        for i in range(7):
            sets = QBarSet(curTime.toString("h:mm"))
            sets.append(50750)
            bars.append(sets)

        chart.addSeries(bars)

        y = QValueAxis()
        x = QDateTimeAxis()

        z = QBarCategoryAxis()

        chart.setAxisX(x, series)
        chart.setAxisY(y, series)

        chart.setAxisX(x, trade)
        chart.setAxisY(y, trade)

        chart.setAxisX(x, test)
        chart.setAxisY(y, test)

        chart.setAxisX(z, bars)
        chart.setAxisY(y, bars)

        y.setMax(maxY)
        y.setMin(minY)
        y.setLabelFormat("%i")

        x.setMin(QDateTime.fromMSecsSinceEpoch(min))
        x.setMax(QDateTime.fromMSecsSinceEpoch(max))
        x.setFormat("h:mm")
        x.setTickCount(7)

        # displaying chart
        chart_view = QChartView(chart)
        chart_view.setRenderHint(QPainter.Antialiasing)
        self.setCentralWidget(chart_view)


w = win()
w.show()
app.exec_()

How can I set the x-axis of a QBarSeries to QDateTimeAxis?

The documentation says:

QDateTimeAxis can be used with any QXYSeries. To add a data point to the series, QDateTime::toMSecsSinceEpoch() is used

Since QBarSeries is not a QXYSeries it wont work just like this
