如何在python matplotlib中将标签放置在饼图顶部？

我试图画一个饼图，并在饼上贴上一个标签，但不知道怎么做。 谁能教我如何在馅饼上贴标签吗

下面是数据示例

Group    percent
[0,10]      0
[10,20]     3 
[20,30]    16
[30,40]    11 
[40,50]    23 
[50,60]    5
[60,70]    27

这是我想要的饼图格式。

我确信还有其他方法可以做到这一点，但我的回应是将从Autotext获得的标签更改为我想要添加的标签

fig, ax = plt.subplots(figsize=(10, 7), subplot_kw=dict(aspect="equal"))
data = df['percent']

labels = ['0~10%', '10~20%', '20~30%', '30~40%', '40~50%', '50~60%','60~70%']
colors = ['#fad9c1','#03396c', '#3b5998', '#63ace5', '#adcbe3','#e3f0ff']

def func(pct, allvals):
    absolute = int(round(pct/100.*np.sum(allvals)))
    return "{:.1f}%\n{:d} hr\n".format(pct, absolute)

wedges, texts, autotexts = ax.pie(data, colors=colors, autopct=lambda pct: func(pct, data), textprops=dict(color="black"))    

for i in range(len(labels)):
    tmp = autotexts[i].get_text()
    new_label = labels[i]+'\n'+tmp.split('\n')[1]+'\n'
    autotexts[i].set_text(new_label)
    
plt.setp(autotexts, size=12, weight="bold")

plt.show()

这里有关于您所问问题的文档

fig, ax = plt.subplots(figsize=(10, 7), subplot_kw=dict(aspect="equal"))
data = df['percent']

labels = ['0~10%', '10~20%', '20~30%', '30~40%', '40~50%', '50~60%','60~70%']
colors = ['#fad9c1','#03396c', '#3b5998', '#63ace5', '#adcbe3','#e3f0ff']

def func(pct, allvals):
    absolute = int(round(pct/100.*np.sum(allvals)))
    return "{:.1f}%\n{:d} hr\n".format(pct, absolute)

wedges, texts, autotexts = ax.pie(data, colors=colors, autopct=lambda pct: func(pct, data), textprops=dict(color="black"))    

for i in range(len(labels)):
    tmp = autotexts[i].get_text()
    new_label = labels[i]+'\n'+tmp.split('\n')[1]+'\n'
    autotexts[i].set_text(new_label)
    
plt.setp(autotexts, size=12, weight="bold")

plt.show()
