Question

我有以下代码：

from string import letters 
import numpy as np 
import pandas as pd 
import seaborn as sns 
import matplotlib.pyplot as plt 

sns.set(style="white") 

# Compute the correlation matrix 
df = pd.DataFrame(np.random.randint(0,100,size=(100, 4)), columns=list('ABCD')) 
corr = df.corr() 

# Generate a mask for the upper triangle 
mask = np.zeros_like(corr, dtype=np.bool) 
mask[np.triu_indices_from(mask)] = True 

# Set up the matplotlib figure 
f, ax = plt.subplots(figsize=(11, 9)) 

# Generate a custom diverging colormap 
cmap = sns.diverging_palette(220, 10, as_cmap=True) 

# Draw the heatmap with the mask and correct aspect ratio 
sns.heatmap(corr, mask=mask, cmap=cmap, vmax=.3, 
      square=True, #xticklabels=5, #yticklabels=5, 
      linewidths=.5, cbar_kws={"shrink": .5}, ax=ax) 
plt.show() 

怎么可能给一个额外的传说的地方，情节的，说觉得像正确的：

A: This is my first label 
B: ... 
C: ... 
D: ... 

我还想为关联栏标注简单的“相关性”。这些数据当然不是真实的数据。

关于你的第一个问题，这里是我能够做到的：

import numpy as np 
import pandas as pd 
import seaborn as sns 
import matplotlib.pyplot as plt 
import matplotlib.lines as mlines 

sns.set(style="white") 

cols = list('ABCD') 
# Compute the correlation matrix 
df = pd.DataFrame(np.random.randint(0,100,size=(100, 4)), columns=cols) 
corr = df.corr() 

# Generate a mask for the upper triangle 
mask = np.zeros_like(corr, dtype=np.bool) 
mask[np.triu_indices_from(mask)] = True 

# Set up the matplotlib figure 
f, ax = plt.subplots(figsize=(11, 9)) 

# Generate a custom diverging colormap 
cmap = sns.diverging_palette(220, 10, as_cmap=True) 

# Draw the heatmap with the mask and correct aspect ratio 
sns.heatmap(corr, mask=mask, cmap=cmap, vmax=.3, 
      square=True, #xticklabels=5, #yticklabels=5, 
      linewidths=.5, cbar_kws={"shrink": .5}, ax=ax) 
pseudo_lines = [] 
strs = ['first', 'second', 'third', 'fourth'] 
for c, s in zip(cols, strs): 
    line = mlines.Line2D([], [], color='blue', 
     marker=r"${}:.This.is.my.{}.label$".format(c, s), 
     markersize=170, linestyle = 'None') 
    pseudo_lines.append(line) 
plt.legend(handles=pseudo_lines, labelspacing=2) 

plt.show()
