我编写了使用 xlsxwriter 模块生成图形的小脚本。它默认采用 x 和 y 轴的值。我想自定义这些值。谁能指出我来解决这个问题。截至目前，对于 X 轴，它需要 -300 到 300 和 Y 轴 0 到 300，但我正在寻找 Y 轴 -100，间隔为 2 到 100，X 到 0 到 -100，间隔。

谢谢您的回复。刚刚编辑了我的问题，例如 x 和 y 轴[-100,98...0,100]

编辑另一个问题：我们可以放大或缩小由 xlsx writer 创建的图形吗

一种选择是，更改 Excel 公式，但它也会更改图表并且对我不起作用。或者换个说法，Can I do zoom in of existing excel chart

使用set_x_axis()和set_y_axis()方法：

chart.set_x_axis({'min': -100, 'max': 0})
chart.set_y_axis({'min': -100, 'max': 100})

要在轴上使用间隔，请查看“major_unit”。

https://xlsxwriter.readthedocs.io/chart.html#major_unit

下面以上面的基本示例为例，将 y 轴上的间隔从“auto”（在本示例中等于 2）更改为 4：

import xlsxwriter

workbook = xlsxwriter.Workbook('chart.xlsx')
worksheet = workbook.add_worksheet()

# Create a new Chart object.
chart = workbook.add_chart({'type': 'column'})

# Write some data to add to plot on the chart.
data = [
    [1, 2, 3, 4, 5],
    [2, 4, 6, 8, 10],
    [3, 6, 9, 12, 15],
]

worksheet.write_column('A1', data[0])
worksheet.write_column('B1', data[1])
worksheet.write_column('C1', data[2])

# Configure the chart. In simplest case we add one or more data series.
chart.add_series({'values': '=Sheet1!$A$1:$A$5'})
chart.add_series({'values': '=Sheet1!$B$1:$B$5'})
chart.add_series({'values': '=Sheet1!$C$1:$C$5'})

# major_unit sets the interval for the axis, overriding the default of 'auto'
chart.set_y_axis({'major_unit': 4})

# Insert the chart into the worksheet.
worksheet.insert_chart('A7', chart)

workbook.close()
