如何在matplotlib中删除上轴和右轴? [英] How can I remove the top and right axis in matplotlib?

问题描述

我希望只使用左轴和底轴，而不是默认的装箱"轴样式:

Instead of the default "boxed" axis style I want to have only the left and bottom axis, i.e.:

+------+         |
|      |         |
|      |   --->  |
|      |         |
+------+         +-------

这应该很容易，但是我在文档中找不到必要的选项.

This should be easy, but I can't find the necessary options in the docs.

推荐答案

这是官方网站这里:

import numpy as np
import matplotlib.pyplot as plt

x = np.linspace(0, 2*np.pi, 100)
y = np.sin(x)

ax = plt.subplot(111)
ax.plot(x, y)

# Hide the right and top spines
ax.spines['right'].set_visible(False)
ax.spines['top'].set_visible(False)

# Only show ticks on the left and bottom spines
ax.yaxis.set_ticks_position('left')
ax.xaxis.set_ticks_position('bottom')

plt.show()
