在Python XlsxWriter中如何将带有日期的X轴设置为文本轴？

Question

我有一些每周时间序列数据，我想要绘制图表。我只希望时间序列中的日期显示在图表中，即我不希望Excel在时间序列中的日期之间插入空点。

我尝试将text_axis明确设置为True，date_axis设置为False，但我最终得到了自动轴和空点：

如果我然后手动将Axis类型设置为文本，那么我就会得到我想要的内容：

这是在第一个屏幕截图中创建图表的代码：

import pandas as pd

# Create a Pandas series with a date index

data = pd.Series([1, 5, 7, 2, 6, 6],
                 index=pd.to_datetime(['2012-10-08',
                                       '2012-10-15',
                                       '2012-10-22',
                                       '2012-10-29',
                                       '2012-11-05',
                                       '2012-11-12']))

writer = pd.ExcelWriter('test.xlsx', engine='xlsxwriter')

df = pd.DataFrame(data)

# Stick it in Excel

worksheet_name = 'test'

df.to_excel(writer, worksheet_name)

# Create a graph

workbook = writer.book
chart = workbook.add_chart({'type': 'column'})

chart.add_series({'values': '={worksheet_name}!$B$2:$B$7'.format(worksheet_name=worksheet_name),
                  'categories': '={worksheet_name}!$A$2:$A$7'.format(worksheet_name=worksheet_name)})

# Set the X axis to be a text axis

chart.set_x_axis({'name': 'Week', 'text_axis': True, 'date_axis': False})

# Stick the graph in Excel

sheets = [sheet for sheet in workbook.worksheets() if sheet.name == worksheet_name]
sheets[0].insert_chart('D2', chart)

# Make the date column wide enough for the date to be visible
sheets[0].set_column(0, 0, 20)

知道我做错了吗？

这是我的坏事。

我的VirtualEnv中是旧版本的XlsxWriter。该模块的作者约翰麦克纳马拉让我正确，它现在正在工作。我的小学生错误！
