如何在Matplotlib中设置图形标题和轴标签的字体大小? [英] How do I set the figure title and axes labels font size in Matplotlib?

问题描述

我正在Matplotlib中创建一个图形，如下所示:

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')

我想为图形标题和轴标签指定字体大小.我需要所有三种字体大小都不同，所以我不需要设置全局字体大小(mpl.rcParams['font.size']=x).如何分别设置图形标题和轴标签的字体大小?

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?

推荐答案

处理诸如label，title等文本的功能接受与

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')

对于全局设置title和label大小， mpl.rcParams 包含和axes.labelsize. (来自页面):

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

(据我所知，无法单独设置x和y标签大小.)

(As far as I can see, there is no way to set x and y label sizes separately.)

我发现axes.titlesize不会影响suptitle.我想，您需要手动设置.

And I see that axes.titlesize does not affect suptitle. I guess, you need to set that manually.
