seaborn heatmap中显示数字

sns.heatmap(corrmat, vmax=1., annot = True, square=True)
控制数字显示的是annot这个参数

corrmat = X[[
    'fuzawangluo16',
    'fuzawangluo2',
    'fuzawangluo5',
    'fuzawangluo19',
    'fuzawangluo6',
    'fuzawangluo20',
    'fuzawangluo17',
    'fuzawangluo3'
]].corr(method='spearman')

plt.figure(figsize=(10,10))
sns.heatmap(corrmat, vmax=1., annot = True, square=True)
plt.title('Important Variables Correlation', fontsize=15)
plt.yticks(rotation=0)
plt.xticks(rotation=90)
plt.show()
