Python | 使用XlsxWriter模块在Excel工作表中绘制饼图

XlsxWriter是一个用于创建Excel XLSX文件的Python模块。它可以在Excel工作表中创建丰富的格式。本文将介绍如何在Excel工作表中创建饼图。

步骤

1. 安装XlsxWriter模块：

   !pip install XlsxWriter
   

2. 创建Excel xlsx文件：

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

3. 创建饼图：

   chart = workbook.add_chart({'type': 'pie'})
   
   # Add data to chart
   chart.add_series({
       'name': 'Sales data',
       'categories': ['Sheet1', 1, 0, 5, 0],
       'values': ['Sheet1', 1, 1, 5, 1],
   })
   
   # Add a title to the chart
   chart.set_title({'name': 'Sales data by region'})
   
   # Insert the chart into the worksheet
   worksheet.insert_chart('B7', chart)
   

4. 关闭Excel文件：

   workbook.close()
   

代码

完整的代码：

import xlsxwriter

# Create an new Excel file and add a worksheet.
workbook = xlsxwriter.Workbook('chart.xlsx')
worksheet = workbook.add_worksheet()

# Add some data.
worksheet.write('A1', 'Region')
worksheet.write('B1', 'Sales')
worksheet.write('A2', 'North')
worksheet.write('A3', 'South')
worksheet.write('A4', 'East')
worksheet.write('A5', 'West')
worksheet.write('B2', 100)
worksheet.write('B3', 200)
worksheet.write('B4', 150)
worksheet.write('B5', 75)

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

# Add data to chart.
chart.add_series({
    'name': 'Sales data',
    'categories': ['Sheet1', 1, 0, 4, 0],
    'values': ['Sheet1', 1, 1, 4, 1],
})

# Add a title to the chart.
chart.set_title({'name': 'Sales data by region'})

# Insert the chart into the worksheet.
worksheet.insert_chart('B7', chart)

# Close the workbook.
workbook.close()
