Python第三方库之openpyxl(5)-优快云博客

本文详细介绍了如何使用 Python 的 openpyxl 库创建气泡图，气泡图是一种三维散点图，通过不同大小的气泡展示数据集之间的关系。文章提供了完整的代码示例，演示了如何添加数据系列、设置样式以及保存图表。

气泡图

气泡图类似于散点图，但使用第三个维度来确定气泡的大小，图表可以包括多个项目

from openpyxl import Workbook
from openpyxl.chart import Series, Reference, BubbleChart

wb = Workbook()
ws = wb.active

rows = [

    ws.append(row)
