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

There is a simpler way actually. I just found:

import matplotlib.pyplot as plt # We prepare the plot   fig, ax = plt.subplots()  # We change the fontsize of minor ticks label  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.
