Increase tick label font size in seaborn

Question

I have a huge problem with my seaborn plots. For some reason, the numbers along the axis are printed with a really small font, which makes them unreadable. I\'ve tried to scale

Answer 1

• This answer will address setting x or y ticklabel size independently.
• sns.set(font_scale=2) from p-robot will set all the figure fonts.
• The answer from Kabir Ahuja works because y-labels position is being used as the text.
  • If there are y-labels text, that solution will not work.

Given the following plot

import matplotlib.pyplot as plt
import seaborn as sns

# data
tips = sns.load_dataset("tips")

# plot figure
plt.figure(figsize=(8, 6))
p = sns.violinplot(x="day", y="total_bill", data=tips)

# get label text
_, ylabels = plt.yticks()
_, xlabels = plt.xticks()
plt.show()

yl = list(ylabels)
print(yl)
>>>[Text(0, -10.0, ''),
Text(0, 0.0, ''),
Text(0, 10.0, ''),
Text(0, 20.0, ''),
Text(0, 30.0, ''),
Text(0, 40.0, ''),
Text(0, 50.0, ''),
Text(0, 60.0, ''),
Text(0, 70.0, '')]

# see that there are no text labels
print(yl[0].get_text())
>>> ''

# see that there are text labels on the x-axis
print(list(xlabels))
>>> [Text(0, 0, 'Thur'), Text(1, 0, 'Fri'), Text(2, 0, 'Sat'), Text(3, 0, 'Sun')]

# the answer from Kabir Ahuja works because of this
print(p.get_yticks())
>>> array([-10.,   0.,  10.,  20.,  30.,  40.,  50.,  60.,  70.])

# in this case, the following won't work because the text is ''
# this is what to do if the there are text labels
p.set_yticklabels(ylabels, size=15)

# set the x-axis ticklabel size
p.set_xticklabels(xlabels, size=5)

• There are no ytick labels because
  • y_text = [x.get_text() for x in ylabels] = ['', '', '', '', '', '', '', '', '']

To set yticklabel size

# use
p.set_yticklabels(p.get_yticks(), size=15)

# or
_, ylabels = plt.yticks()
p.set_yticklabels(ylabels, size=15)

To set xticklable size

# use
p.set_xticklabels(p.get_xticks(), size=15)

# or
_, xlabels = plt.xticks()
p.set_xticklabels(xlabels, size=15)

With the given plot

# set the y-labels with
p.set_yticklabels(p.get_yticks(), size=5)

# set the x-labels with
_, xlabels = plt.xticks()
p.set_xticklabels(xlabels, size=5)
