Question

我编写了一个小脚本，它使用xlsxwriter模块生成图形。它采用x和y轴的默认值。我想定制这些价值。任何人都可以指出我解决这个问题。截至目前，对于X轴，它需要-300到300，Y轴需要0到300，但我正在寻找Y轴-100，其中2个间隔为100，X为0到-100，间隔为。

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

编辑还有一个问题：我们可以放大或缩小由其创建的图形 xlsx作家

一个选项是，更改Excel公式但它也会更改图形，但对我来说不起作用。或者换句话说，Can I do zoom in of existing excel chart

Answer 1

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})

Answer 2

要在轴上使用间隔，请查看＆＃39; major_unit＆＃39;。

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

以下是上面的基本示例，并更改了自动＆＃39;的间隔。（在本例中等于2）到y轴上的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()

在xlsxwriter中自定义X和Y轴值
