我正在尝试绘制一个矩阵来比较一些数据。但情节标题与子情节重叠:

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

def save_graph_cm(CMatrix):
# CMatrix is a dict with four 3x3 pandas DataFrame
k = 'Wine'
id = 0
cm = 1
plt.suptitle("#" + str(id) + " Confusion Matrix for " + k + " dataset")
for c_matrix in CMatrix:
plt.subplot(2, 2, cm)
sn.heatmap(CMatrix[c_matrix], annot=True, cmap="YlOrRd")
plt.title("CV - " + str(cm-1))
plt.xlabel("Predicted Classes")
plt.ylabel("Real Classes")
cm += 1
plt.tight_layout()
plt.show

我现在得到的是:

最佳答案

截至v3.3 ,matplotlib 的 tight_layout 现在可以正确显示 suptitle:

import matplotlib.pyplot as plt

fig, axs = plt.subplots(1, 3)
for i, ax in enumerate(axs):
ax.plot([1, 2, 3])
ax.set_title(f'Axes {i}')

fig.suptitle('suptitle')
fig.tight_layout()

enter image description here
