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 = [
    ("Number of Products", "Sales in USD", "Market share"),
    (14, 12200, 15),
    (20, 60000, 33),

    (12, 8200, 18),
    (15, 50000, 30),
    (19, 22400, 15),
    (25, 25000, 50),
]

for row in rows:
    ws.append(row)

chart = BubbleChart()
chart.style = 18 # use a preset style

# add the first series of data
xvalues = Reference(ws, min_col=1, min_row=2, max_row=5)

# place the chart starting in cell E1
ws.add_chart(chart, "E1")
