matlibplot:如何在一些子图之间添加空格 [英] matlibplot: How to add space between some subplots

问题描述

如何调整某些子图之间的空白?在下面的示例中，假设我要消除第一子图和第二子图之间以及第三子图和第四子图之间的所有空白，并增加第二子图和第三子图之间的空间?

How can I adjust the whitespace between some subplots? In the example below, let's say I want to eliminate all whitespace between the 1st and 2nd subplots as well as between the 3rd and 4th and increase the space between the 2nd and 3rd?

import matplotlib.pyplot as plt
import numpy as np

# Simple data to display in various forms
x = np.linspace(0, 2 * np.pi, 400)
y = np.sin(x ** 2)

f, ax = plt.subplots(4,figsize=(10,10),sharex=True)

ax[0].plot(x, y)
ax[0].set_title('Panel: A')

ax[1].plot(x, y**2)

ax[2].plot(x, y**3)
ax[2].set_title('Panel: B')
ax[3].plot(x, y**4)

plt.tight_layout() 

推荐答案

为了使解决方案接近您的代码，您可以使用创建 5 个子图，其中中间的一个是其他子图的四分之一，然后删除中间的图.

To keep the solution close to your code you may use create 5 subplots with the middle one being one forth in height of the others and remove that middle plot.

import matplotlib.pyplot as plt
import numpy as np

# Simple data to display in various forms
x = np.linspace(0, 2 * np.pi, 400)
y = np.sin(x ** 2)

f, ax = plt.subplots(5,figsize=(7,7),sharex=True, 
                     gridspec_kw=dict(height_ratios=[4,4,1,4,4], hspace=0))

ax[0].plot(x, y)
ax[0].set_title('Panel: A')

ax[1].plot(x, y**2)

ax[2].remove()

ax[3].plot(x, y**3)
ax[3].set_title('Panel: B')
ax[4].plot(x, y**4)


plt.tight_layout()
plt.show()
