Python:如何增加/减少x和y刻度标签的字体大小? [英] Python: How to increase/reduce the fontsize of x and y tick labels?

问题描述

在使用matplotlib时如何弄清楚x和y刻度标签的fontsize似乎有问题.

I seem to have a problem in figuring out how to increase or decrease the fontsize of both the x and y tick labels while using matplotlib.

我知道有set_xticklabels(labels, fontdict=None, minor=False, **kwargs)函数，但是我不明白如何控制其中的fontsize.

I am aware that there is the set_xticklabels(labels, fontdict=None, minor=False, **kwargs) function, but I failed to understand how to control the fontsize in it.

我希望某些明确的东西，例如

I expected something somehow explicit, like

title_string=('My Title')
plt.suptitle(title_string, y=1.0, fontsize=17)

但是到目前为止，我还没有找到类似的东西.我想念什么?

but I haven't found anything like that so far. What am I missing?

推荐答案

您可以直接在对set_xticklabels和set_yticklabels的调用中设置字体大小(如先前的回答所述).一次只会影响一个Axes.

You can set the fontsize directly in the call to set_xticklabels and set_yticklabels (as noted in previous answers). This will only affect one Axes at a time.

ax.set_xticklabels(x_ticks, rotation=0, fontsize=8)
ax.set_yticklabels(y_ticks, rotation=0, fontsize=8)

您还可以使用ticklabel字体大小(即，针对脚本中的所有图形/子图). > rcParams :

You can also set the ticklabel font size globally (i.e. for all figures/subplots in a script) using rcParams:

import matplotlib.pyplot as plt

plt.rc('xtick',labelsize=8)
plt.rc('ytick',labelsize=8)

或者，等效地:

plt.rcParams['xtick.labelsize']=8
plt.rcParams['ytick.labelsize']=8

最后，如果要为所有matplotlib图设置此设置，则还可以在matplotlibrc文件中设置这两个rcParams:

Finally, if this is a setting that you would like to be set for all your matplotlib plots, you could also set these two rcParams in your matplotlibrc file:

xtick.labelsize      : 8 # fontsize of the x tick labels
ytick.labelsize      : 8 # fontsize of the y tick labels
