This is the suggested Matplotlib 3 solution from the official website <a href="http://matplotlib.org/examples/ticks_and_spines/spines_demo.html" rel="noreferrer">HERE</a>:

<pre><code>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()
</code></pre>

Alternatively, this

<pre><code>def simpleaxis(ax):
 ax.spines['top'].set_visible(False)
 ax.spines['right'].set_visible(False)
 ax.get_xaxis().tick_bottom()
 ax.get_yaxis().tick_left()
</code></pre>

seems to achieve the same effect on an axis without losing rotated label support.

[edit] matplotlib in now (2013-10) on version 1.3.0 which includes this

That ability was actually just added, and you need the Subversion version for it. You can see the example code <a href="http://matplotlib.org/examples/pylab_examples/spine_placement_demo.html" rel="nofollow noreferrer">here</a>.

I am just updating to say that there's a better <a href="https://github.com/ericliang/matplotlib/blob/master/tags/v0_99_0/examples/axes_grid/simple_axisline3.py" rel="nofollow noreferrer">example</a> online now. Still need the Subversion version though, there hasn't been a release with this yet.

[edit] Matplotlib 0.99.0 RC1 was just released, and includes this capability.

Library Seaborn has this built in with function <code>.despine()</code>.
Just add:
<pre><code>import seaborn as sns
</code></pre>
Now create your graph. And add at the end:
<pre><code>sns.despine()
</code></pre>
If you look at some of the default parameter values of the function it removes the top and right spine and keeps the bottom and left spine:
<pre><code>sns.despine(top=True, right=True, left=False, bottom=False)
</code></pre>

blocks|key|1329878|text|如果需要将其从所有绘图中删除，可以在样式设置(样式表或rcParams)中删除脊线。例如：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1329879|import+matplotlib+as+mpl

If you need to remove it from all your plots, you can remove spines in style settings (style sheet or rcParams). E.g:

<pre><code>import matplotlib as mpl

mpl.rcParams['axes.spines.right'] = False
mpl.rcParams['axes.spines.top'] = False
</code></pre>

If you want to remove all spines:

<pre><code>mpl.rcParams['axes.spines.left'] = False
mpl.rcParams['axes.spines.right'] = False
mpl.rcParams['axes.spines.top'] = False
mpl.rcParams['axes.spines.bottom'] = False
</code></pre>

blocks|key|1329693|text|如果您不需要刻度之类的标记(例如，用于绘制定性插图)，您也可以使用此快速解决方法：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1329694|使轴不可见(例如，使用plt.gca().axison+=+False)，然后使用plt.arrow手动绘制它们。|offset|length|style|CODE|1329695|entityMap^0|0|B|O|15|9|0^^$0|@$1|2|3|4|5|6|7|J|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|K|8|@$D|L|E|M|F|G]|$D|N|E|O|F|G]]|9|@]|A|$]]|$1|H|3|-4|5|6|7|P|8|@]|9|@]|A|$]]]|I|$]]

If you don't need ticks and such (e.g. for plotting qualitative illustrations) you could also use this quick workaround: 

Make the axis invisible (e.g. with <code>plt.gca().axison = False</code>) and then draw them manually with <code>plt.arrow</code>.

blocks|key|1545160|text|另一种以非全局方式完成此操作的方法是使用matplotlib.pyplot.rc_context上下文管理器，如下所示：|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1545161|with+plt.rc_context({
++++"axes.spines.right":+False,
++++"axes.spines.top":+False,

Another way of doing this in a non-global way is using the <a href="https://matplotlib.org/stable/api/_as_gen/matplotlib.pyplot.rc_context.html" rel="nofollow noreferrer"><code>matplotlib.pyplot.rc_context</code></a> context manager, as follows:
<pre><code>with plt.rc_context({
 &quot;axes.spines.right&quot;: False,
 &quot;axes.spines.top&quot;: False,
}):
 fig, ax = plt.subplots()
 ...
</code></pre>

blocks|key|1545223|text|如果您想要频繁地应用此设置，您还可以创建一个如here所述的样式表，并使用以下设置：|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|1545224|axes.spines.left:+++True
axes.spines.bottom:+True
axes.spines.top:++++False
axes.spines.right:++False|code-block|syntax|javascript|1545225|entityMap|0|LINK|mutability|MUTABLE|url|https://matplotlib.org/stable/tutorials/introductory/customizing.html#customizing-with-style-sheets^0|N|4|0|0|0^^$0|@$1|2|3|4|5|6|7|Q|8|@]|9|@$A|R|B|S|1|T]]|C|$]]|$1|D|3|E|5|F|7|U|8|@]|9|@]|C|$G|H]]|$1|I|3|-4|5|6|7|V|8|@]|9|@]|C|$]]]|J|$K|$5|L|M|N|C|$O|P]]]]

In case you want to apply this on a frequent basis, you can also create a style sheet as described <a href="https://matplotlib.org/stable/tutorials/introductory/customizing.html#customizing-with-style-sheets" rel="nofollow noreferrer">here</a> and use these settings:
<pre><code>axes.spines.left: True
axes.spines.bottom: True
axes.spines.top: False
axes.spines.right: False
</code></pre>

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

<pre><code>+------+ |
| | |
| | ---&gt; |
| | |
+------+ +-------
</code></pre>

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

How can I remove the top and right axis in matplotlib?

我希望只有左轴和底轴，而不是默认的“长方体”轴样式，即：+------+         ||      |         ||      |   --->  ||      |         |+------+         +-------这应该很简单，但我在文档中找不到必要的选项。
