Candlestick is not showing without data

[tuai]

Hello i am new to using Qt5,
I'm trying to make a candlestick chart but can't get my data on the chart, can someone tell me what I'm doing wrong?

Dataset:
Date,Open,High,Low,Close,Adj Close,Volume
2020-01-01,7194.892090,7254.330566,7174.944336,7200.174316,7200.174316,18565664997
more data ...

def create_candle_chart(self, symbol):
        series = QtCharts.QCandlestickSeries()
        series.setIncreasingColor(Qt.green)
        series.setDecreasingColor(Qt.red)

        with open('ETH-USD-29_SEP_2021-10_NOV_2021.csv', 'r') as csvFile:
            csvReader = csv.reader(csvFile, delimiter=",")
            horizontal_list = list()
            for row in csvReader:
                set = QtCharts.QCandlestickSet()
                horizontal_list.append(row[0])
                set.open = float(row[1])
                set.high = float(row[2])
                set.low = float(row[3])
                set.close = float(row[4])
                series.append(set)

            candleChart = QtCharts.QChart()
            candleChart.addSeries(series)
            candleChart.createDefaultAxes()
            candleChart.setTitle('Candlestick')
            candleChart.setAnimationOptions(QtCharts.QChart.AllAnimations)
            candleChart.setTheme(QtCharts.QChart.ChartThemeDark)
            candleChart.axisX(series).setCategories(horizontal_list)

            candleChart.setVisible(True)

            chart_view = QtCharts.QChartView(candleChart)

            self.ui.candleChart.addWidget(chart_view)

this is what i get:

Hi and welcome to devnet,

What happens if you use the setter of each property ?

On a side note, set is a Python keyword, you should either use a more relevant variable name or use set_ to avoid replacing the original set type.
