heatmap annotation font size

I am creating a heatmap with sns.heatmap() but couldn’t find a way to set the size of the labels inside the boxes when we set annot=True, is it possible to make the font smaller ?

Thanks

Use the annot_kws parameter, e.g.

sns.heatmap(x, annot=True, annot_kws={"size": 20})

@shayan911 each of the ticklabel is also an object and you can use .set_fontsize() method for it. Make sure you have set_ticklabels() first.

import matplotlib.pyplot as plt
x = [1, 2, 3]
y = [2, 4.5, 4]

fig, ax = plt.subplots()
ax.plot(x, y)

ax.set_xticks(x)
ax.set_xticklabels(x)

for label in ax.xaxis.get_ticklabels():
    if label.get_text() == '2':
        label.set_fontsize(20)
