How to change the font size on a matplotlib plot
How does one change the font size for all elements (ticks, labels, title) on a matplotlib plot?
I know how to change the tick label sizes, this is done with:
import matplotlib
matplotlib.rc('xtick', labelsize=20)
matplotlib.rc('ytick', labelsize=20)
But how does one change the rest?
From the matplotlib documentation,
font = {'family' : 'normal',
'weight' : 'bold',
'size' : 22}
matplotlib.rc('font', **font)
This sets the font of all items to the font specified by the kwargs object, font .
Alternatively, you could also use the rcParams update method as suggested in this answer:
matplotlib.rcParams.update({'font.size': 22})
You can find a full list of available properties on the Customizing matplotlib page.
matplotlib.rcParams.update({'font.size': 22})
如果您想要将字体大小更改为已创建的特定绘图，请尝试以下操作：
import matplotlib.pyplot as plt
ax = plt.subplot(111, xlabel='x', ylabel='y', title='title')
for item in ([ax.title, ax.xaxis.label, ax.yaxis.label] +
ax.get_xticklabels() + ax.get_yticklabels()):
item.set_fontsize(20)
