带有第二个 y 轴的 Seaborn 图

i wanted to know how to make a plot with two y-axis so that my plot that looks like this :

to something more like this by adding another y-axis :

我只使用图中的这行代码，以便从我的数据框中获取前 10 个引擎版本：

sns.countplot(x='EngineVersion', data=train, order=train.EngineVersion.value_counts().iloc[:10].index);

我认为您正在寻找类似的东西：

import matplotlib.pyplot as plt
x = [1,2,3,4,5]
y = [1000,2000,500,8000,3000]
y1 = [1050,3000,2000,4000,6000]

fig, ax1 = plt.subplots()

ax2 = ax1.twinx()
ax1.bar(x, y)
ax2.plot(x, y1, 'o-', color="red" )

ax1.set_xlabel('X data')
ax1.set_ylabel('Counts', color='g')
ax2.set_ylabel('Detection Rates', color='b')

plt.show()

Output:
