如何将 chart.y_axis 类别更改为数字

Question

我正在尝试将 x_axis 类别更改为数字，因为图表如下所示。这是我在 python 中使用 openpyxl

的代码

        chart = LineChart()
        chart.title = f'{key}-{date()}'
        chart.height = 14
        chart.width = 30
        chart.y_axis = Typed(expected_type=NumericAxis)
        data = Reference(ws, min_col=2, min_row=1, max_row=y, max_col=z)
        cats = Reference(ws, min_col=1, min_row=2, max_row=y, max_col=1)
        chart.add_data(data, titles_from_data=True)
        chart.set_categories(cats)
        ws.add_chart(chart, "B2")
        writer.save()

（我想要的是显示数字，如“50000000”而不是“5E+09”）

解决方案：-将所有单元格格式更改为数字

    df.to_excel(writer, sheet_name='`sheets name`')
    y = len(df.index)
    z = len(df.columns)
    writer = pd.ExcelWriter('`filename`', engine='openpyxl')
    ws = writer.sheets['`sheets name`']
    for i in range(1, z):
        for e in range(1, y):
            cell = ws.cell(e, i)
            cell.number_format = '0'
