Matplotlib make tick labels font size smaller

Question

In a matplotlib figure, how can I make the font size for the tick labels using ax1.set_xticklabels() smaller?

Further, how can one rotate it from horizontal to vertical?

Answer 1

You can use the below-mentioned code to make tick labels font size smaller in Matplotlib:

import matplotlib.pyplot as plt 

ax = plt.subplots() 

ax.tick_params(axis='both', which='major', labelsize=10) 

ax.tick_params(axis='both', which='minor', labelsize=8)

This only answers to the size of label part of your question though.
