Change the font size of labels in sns.heatmap

[hasti_hakhamanesh]

my code is as following:

fig, ax = plt.subplots()
st.write('1.3')
sns.set(font_scale=1.3)
sns.heatmap(df_.corr(),annot=True, annot_kws={'size': 0.01},cmap='BrBG')
 #plt.xlabel('Mathematical Expression', fontsize=1)
 st.write(fig)

really the size of x and y labels is so big i change the parameter font_scale but not working well for me

my question is: how can i change the labels font size?

thanks in advance

sns.set(font_scale=1.3) does change the x and y labels font size. I am not sure what you mean by “not working well for me” but if you think the labels are too big, making them bigger is not going to help.
