python - Wrapping long y labels in matplotlib tight layout using setp -

-

i've been trying wrap text long labels in code. tried textwrap method suggested earlier here, code defines yticklabels through array imported csv using pyplot.setp() method. i'm using tight_layout() formatting otherwise.

so question - there way wrap long y labels newlines easily?

here sample code i'd fix for:

import numpy np import matplotlib.pyplot plt  labels=('really really really long label 1', 'really really really long label 2', 'really really really long label 3') values=(30,50,40)  fig = plt.figure() ax=fig.add_subplot(111)  plt.ylim((0,40)) in np.arange(3):     plt.barh(15*i, values[i])  plt.yticks(15*np.arange(3)) plt.setp(ax.set_yticklabels(labels))  plt.tight_layout() plt.show()

this plots enter image description here i'd labels go newlines after fixed width. ideas?

i have tried using textwrap on labels , works me.

from textwrap import wrap labels=['really really really long label 1',         'really really really long label 2',         'really really really long label 3'] labels = [ '\n'.join(wrap(l, 20)) l in labels ]

inserting in code gives us:

wrapped labels
