matplotlib plt未在散点图上正确设置xlabel/ylabel

Question

我正在创建一个地理地块，并尝试设置我的XLabel和Ylabel。它只显示ylabel，而不显示xlabel。这是一个最小的可重复的例子

import pandas as pd
import matplotlib.pyplot as plt
import numpy as np

d = {
    'College': ['East Los Angeles College', 'Santa Monica Ccollege', 'American River College', 'Santa Ana College', 'Mount San Antonio College'],
    'Total Enrollment': [36606, 29999, 29701, 28698, 28481], 
    'Latitude': [34.0414, 34.0166, 38.6511, 33.7580, 34.0482],
    'Longitude': [-118.1503, -118.4704, -121.3467, -117.8889, 117.8451]
}
df = pd.DataFrame(data=d)
ax2 = df.plot.scatter(x='Longitude', y='Latitude',
                     s=df['Total Enrollment']/100, label='Enrollment',
                     c='Total Enrollment', cmap=plt.get_cmap("jet"),
                     colorbar=True, alpha=0.5, figsize=(15,12))

plt.ylabel("Latitude", fontsize=14)
plt.xlabel("Longitude", fontsize=14)

plt.legend(fontsize=16)
plt.show()

Answer 1

添加以下行似乎适合我：

fig, ax = plt.subplots()
...
df.plot.scatter(..., ax=ax)

ax.set_ylabel("Latitude", fontsize=14)
ax.set_xlabel("Longitude", fontsize=14)

尽管如this question中所述，调用plt.subplots并指定轴似乎是缺少的链接
