Python 饼图不包括所有数据

我在官方文档中创建了饼图。这是我的密码

1  pie = PieChart() 
2  labels = Reference(sheet, min_col=2, min_row=1, max_row=5)
3  data = Reference(sheet, min_col=3, min_row=1, max_row=5)
4  pie.add_data(data, titles_from_data=True)
5  pie.set_categories(labels)
6  pie.title = "What did you like best about SKY Schools?"
7  sheet.add_chart(pie, "E1")                                                                                                              

这是Excel和饼图中的数据

饼图并没有选取最后一个数据点：“金钥匙”。我阅读了对象的文档，但无法理解是什么导致了问题。在第2行和第3行中，我将max_rows值调整了1，但没有解决

任何帮助/想法？

titles\u from\u data=True

用于指定第一项数据（单元格C1）为标题

然而，看看你的截图，没有标题。因此，您可以将其设置为false，也可以根本不设置参数

重新创建屏幕截图：

from openpyxl import Workbook

from openpyxl.chart import (
    PieChart,
    ProjectedPieChart,
    Reference
)
from openpyxl.chart.series import DataPoint

data = [ 
    ['What did you like best about SKY Schools?', 'Games', 48],
    ['What did you like best about SKY Schools?', 'All of it', 36],
    ['What did you like best about SKY Schools?', 'Breathing', 25],
    ['What did you like best about SKY Schools?', 'Yoda', 23],
    ['What did you like best about SKY Schools?', 'The Golden Keys', 16]
]

wb = Workbook()
ws = wb.active

for row in data:
    ws.append(row)

ws.merge_cells('A1:A5')

pie = PieChart()
labels = Reference(ws, min_col=2, min_row=1, max_row=5)
data = Reference(ws, min_col=3, min_row=1, max_row=5)
pie.add_data(data)
pie.set_categories(labels)
pie.title = ws.cell(1, 1).value
ws.add_chart(pie, "E1")
wb.save("results.xlsx")

要包括第5行，您需要将max_row设置为6。@Greg谢谢。我这样做了，但没有解决问题。

titles\u from\u data=True

是罪魁祸首。谢谢你的帮助。
