在 Seaborn Barplot 上标记轴 [英] Label axes on Seaborn Barplot

问题描述

我正在尝试通过以下代码将自己的标签用于Seaborn barplot:

I'm trying to use my own labels for a Seaborn barplot with the following code:

import pandas as pd
import seaborn as sns

fake = pd.DataFrame({'cat': ['red', 'green', 'blue'], 'val': [1, 2, 3]})
fig = sns.barplot(x = 'val', y = 'cat', 
                  data = fake, 
                  color = 'black')
fig.set_axis_labels('Colors', 'Values')

但是，我收到一个错误消息:

However, I get an error that:

AttributeError: 'AxesSubplot' object has no attribute 'set_axis_labels'

有什么作用?

推荐答案

Seaborn的条形图返回轴对象(不是图形).这意味着您可以执行以下操作:

Seaborn's barplot returns an axis-object (not a figure). This means you can do the following:

import pandas as pd
import seaborn as sns
import matplotlib.pyplot as plt

fake = pd.DataFrame({'cat': ['red', 'green', 'blue'], 'val': [1, 2, 3]})
ax = sns.barplot(x = 'val', y = 'cat', 
              data = fake, 
              color = 'black')
ax.set(xlabel='common xlabel', ylabel='common ylabel')
plt.show()
