气泡图类似于散点图，但使用三维来确定气泡的大小，图表可以包含多个系列。
""" Sample bubble chart """ 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), (18, 24400, 10), (22, 32000, 42), (), (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) yvalues = Reference(ws, min_col=2, min_row=2, max_row=5) size = Reference(ws, min_col=3, min_row=2, max_row=5) series = Series(values=yvalues, xvalues=xvalues, zvalues=size, title="2013") chart.series.append(series) # add the second xvalues = Reference(ws, min_col=1, min_row=7, max_row=10) yvalues = Reference(ws, min_col=2, min_row=7, max_row=10) size = Reference(ws, min_col=3, min_row=7, max_row=10) series = Series(values=yvalues, xvalues=xvalues, zvalues=size, title="2014") chart.series.append(series) # place the chart starting in cell E1 ws.add_chart(chart, "E1") wb.save("bubble.xlsx")这将生成一个包含两个序列的气泡图，应该如下所示：
