Python/Matplotlib - x tick label formatted into multiple columns?

Question

Is it possible to take:

hello world 12345

as an x-tick label (already being displayed vertically) and turn it into this:

hello world
12345

which is an x-tick label with (rotated) two columns?

Answer 1

You could format the text using the textwrap module from the standard library:

import matplotlib.pyplot as plt
import numpy as np
import textwrap
mu, sigma=100, 15
N=4
x=mu + sigma*np.random.randn(N)
plt.bar(range(N), x, align='center')
labels=[
 'hello world 12345',
 'another long one',
 'what happened to pithy',
 'yada yada',
 ]
labels=[textwrap.fill(text,15) for text in labels]
plt.xticks(range(N), labels)
plt.show()
