如何在 matplotlib 中旋轉軸標題？

Question

我無法在 y 軸和 x 軸上旋轉名稱，使它們重疊。 我究竟做錯了什么？

yticks/xticks(rotation=90) 也不會調整名稱以防止它們重疊。

name = 'Anne Frank Diary'
df4 = df.loc[ my_list, my_list ].copy()
axes = pd.plotting.scatter_matrix(df4, figsize=(15, 15), marker='o',hist_kwds={'bins': 20}, s=60, alpha=.8)
corr = df4.corr().values 
for i, j in zip(*plt.np.triu_indices_from(axes, k=1)):
    axes[i, j].annotate("%.3f" %corr[i,j], (0.8, 0.8), xycoords='axes fraction', ha='left', va='center',rotation=90)
sst="%s \n Scatter Matrix of Centrality Indices \n (displaying Pearson correlation coefficients)" %name
plt.suptitle(sst,fontsize=20);

n = len(G.nodes)

for x in range(n):
    for y in range(n):
        # to get the axis of subplots
        ax = axes[x, y]
        # to make x axis name vertical  
        ax.xaxis.label.set_rotation(90)
        # to make y axis name horizontal 
        ax.yaxis.label.set_rotation(0)
        # to make sure y axis names are outside the plot area
        ax.yaxis.labelpad = 10
