I am creating a figure in Matplotlib like this:
from matplotlib import pyplot as plt fig = plt.figure() plt.plot(data) fig.suptitle('test title') plt.xlabel('xlabel') plt.ylabel('ylabel') fig.savefig('test.jpg')
I want to specify font sizes for the figure title and the axis labels. I need all three to be different font sizes, so setting a global font size (mpl.rcParams['font.size']=x
) is not what I want. How do I set font sizes for the figure title and the axis labels individually?

Functions dealing with text like label
, title
, etc. accept parameters same as matplotlib.text.Text
. For the font size you can use size/fontsize
:
from matplotlib import pyplot as plt fig = plt.figure() plt.plot(data) fig.suptitle('test title', fontsize=20) plt.xlabel('xlabel', fontsize=18) plt.ylabel('ylabel', fontsize=16) fig.savefig('test.jpg')
For globally setting title
and label
sizes, mpl.rcParams
contains axes.titlesize
and axes.labelsize
. (From the page):
axes.titlesize : large # fontsize of the axes title axes.labelsize : medium # fontsize of the x any y labels
(As far as I can see, there is no way to set x
and y
label sizes separately.)
And I see that axes.titlesize
does not affect suptitle
. I guess, you need to set that manually.
