为 matplotlib 中的所有子图设置相同的轴限制 [英] Setting the same axis limits for all subplots in matplotlib

问题描述

这个问题似乎很简单，但是我找不到解决该问题的Python方法.我有几个(四个)子图，它们应该具有相同的 xlim 和 ylim .遍历所有子图la

This problem seems simple enough, but I can't find a pythonic way to solve it. I have several (four) subplots that are supposed to have the same xlim and ylim. Iterating over all subplots à la

f, axarr = plt.subplots(4)
for x in range(n):
    axarr[x].set_xlim(xval1, xval2)
    axarr[x].set_ylim(yval1, yval2)

并不是最好的做事方式，尤其是对于2x2的子图–这是我实际上要处理的事情.我正在寻找类似 plt.all_set_xlim(xval1, xval2) 的东西.

isn't the nicest way of doing things, especially for 2x2 subplots – which is what I'm actually dealing with. I'm looking for something like plt.all_set_xlim(xval1, xval2).

请注意，我不想更改任何其他内容(刻度和标签应单独控制).

Note that I don't want anything else to change (ticks and labels should be controlled separately).

我正在使用 plt.subplots(2，2)包装器.遵循dienzs的答案后，我尝试了 plt.subplots(2，2，sharex = True，sharey = True) –几乎是对的，但是现在除了左侧和底部的行以外，所有的刻度都消失了.

I'm using the plt.subplots(2, 2) wrapper. Following dienzs answer, I tried plt.subplots(2, 2,sharex=True, sharey=True) – almost right, but now the ticks are gone except for the left and bottom row.

推荐答案

通过 matplotlib.pyplot.setp 在 Artist 对象上设置 xlim 和 ylim 属性() https://matplotlib.org/3.1.0/api/_as_gen/matplotlib.pyplot.setp.html

Set the xlim and ylim properties on the Artist object by matplotlib.pyplot.setp() https://matplotlib.org/3.1.0/api/_as_gen/matplotlib.pyplot.setp.html

# Importing matplotlib.pyplot package.
import matplotlib.pyplot as plt

# Assigning 'fig', 'ax' variables.
fig, ax = plt.subplots(2, 2)

# Defining custom 'xlim' and 'ylim' values.
custom_xlim = (0, 100)
custom_ylim = (-100, 100)

# Setting the values for all axes.
plt.setp(ax, xlim=custom_xlim, ylim=custom_ylim)
