seaborn histplot - 在每个条形图上方打印 y 值

Question

请问如何在每个条形图上方打印 y 值？谢谢

import matplotlib.pyplot as plt
import seaborn as sns

data = [6, 3, 1, 5, 2, 7, 3, 1, 9, 2, 1, 4, 2, 6, 3, 9, 4, 1, 7, 3, 1, 9, 2, 1, 4, 2, 1, 3, 1, 4, 2, 7, 3, 1, 5, 2, 7, 3, 1, 5, 1, 8, 4, 1, 6, 3, 1, 5, 2, 7, 3, 1, 5, 2, 8, 4, 1, 6, 3, 9, 4, 1, 7, 2, 1, 3, 1, 4, 7, 3, 1, 9, 2, 1, 4, 2, 1, 3, 1, 4, 2, 7, 3, 1, 5, 2, 7, 3, 1, 5, 1, 8, 4, 1, 6, 3, 1, 5, 2, 7, 3, 1, 5, 2, 8, 4, 1, 6, 3, 9, 4, 1, 7, 2, 1, 3, 1, 4, 2, 7, 3, 1, 9, 2, 1, 4, 2, 6, 3, 9, 4, 2, 1, 5, 1, 8, 4, 1, 6, 3, 9, 4, 2, 1, 6, 1, 9, 4, 2, 7, 3, 1, 5, 1, 8, 4, 2, 1, 5, 1, 8, 4, 2, 1, 9, 4, 1, 7, 3, 1, 5, 1, 8, 2, 1, 6, 3, 9, 4, 2, 1, 5, 2, 1, 4, 2, 6, 3, 1, 5, 2, 1, 6, 3, 9, 4, 2, 7, 3, 1, 5, 2, 7, 3, 1, 5, 2, 8, 4, 1, 6, 3, 1, 5, 2, 7, 3, 1, 9, 2, 1, 4, 2, 6, 3, 9, 4, 1, 7, 3, 1, 9, 2, 1, 4, 2, 1, 3, 1, 4, 2, 7, 3, 1, 5, 2, 7, 3, 1, 5, 1, 8, 4, 1, 6, 3, 1, 5, 2]

fig, ax = plt.subplots()

ax = sns.histplot(data, discrete=True, kde=False, stat='percent') 

plt.show()

Answer 1

如果你有 matplotlib 3.4.0 或更高版本，你可以使用 bar_label。更多信息 here

代码应该是这样的...

ax = sns.histplot(data, discrete=True, kde=False, stat='percent') 
ax.bar_label(ax.containers[0])
