[FIXED] Change xticklabels fontsize of seaborn heatmap

Issue

Here is my question:
I plot 7 variable's coefficient using sns.clustermap()

• x/y tickslabel seems really small(In my case, s1,s2,... s9)

My attempt

• label='big ==> no effect
• plt.tick_params(axis='both', which='minor', labelsize=12) ===> cbar label has changed, but the x/y axes looks the same.

Add

My code:

 ds =  pd.read_csv("xxxx.csv")
 corr = ds.corr().mul(100).astype(int)
 
 cmap = sns.diverging_palette(h_neg=210, h_pos=350, s=90, l=30, as_cmap=True)

 sns.clustermap(data=corr_s, annot=True, fmt='d',cmap = "Blues",annot_kws={"size": 16},)

Solution

Consider calling sns.set(font_scale=1.4) before plotting your data. This will scale all fonts in your legend and on the axes.

My plot went from this,

To this,

Of course, adjust the scaling to whatever you feel is a good setting.

Code:

sns.set(font_scale=1.4)
cmap = sns.diverging_palette(h_neg=210, h_pos=350, s=90, l=30, as_cmap=True)
sns.clustermap(data=corr, annot=True, fmt='d', cmap="Blues", annot_kws={"size": 16})
