python - 如何在Matplotlib中设置图标题和轴标签字体大小？(How do I set the figure title and axes labels font size in Matplotlib?)

Question

I am creating a figure in Matplotlib like this:

(我正在Matplotlib中创建一个像这样的人物：)

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.

(我想指定图标题和轴标签的字体大小。)

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.

(我需要三个不同的字体大小，所以设置全局字体大小（ mpl.rcParams['font.size']=x ）不是我想要的。)

How do I set font sizes for the figure title and the axis labels individually?

(如何单独设置图标题和轴标签的字体大小？)

Answer 1

Functions dealing with text like label , title , etc. accept parameters same as matplotlib.text.Text .

(处理label ， title等文本的函数接受与matplotlib.text.Text相同的参数。)

For the font size you can use size/fontsize :

(对于字体大小，您可以使用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 .

(对于全局设置title和label大小， mpl.rcParams包含axes.titlesize和axes.labelsize 。)

(From the page):

(（来自页面）：)

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.)

(（据我所知，没有办法单独设置x和y标签尺寸。）)

And I see that axes.titlesize does not affect suptitle .

(我看到axes.titlesize不会影响suptitle 。)

I guess, you need to set that manually.

(我想，你需要手动设置。)
