plt.hist(x, label = 'something')

我不希望图例某物"旁边的框.如何将其删除?

I don't want the box next to the legend "something". How to remove it?

推荐答案

首先，您可能决定完全不创建图例，而是在图的一角放置一些标签.

First of all, you may decide not to create a legend at all and instead put some label in to corner of the plot.

import matplotlib.pyplot as plt
import numpy as np

x = np.random.normal(size=160)
plt.hist(x)

plt.text(0.95,0.95, 'something', ha="right", va="top", transform=plt.gca().transAxes)
plt.show()

如果您已经创建了图例并想将其删除，则可以通过

If you already created the legend and want to remove it, you can do so by

plt.gca().get_legend().remove()

，然后添加文字.

如果这不是一个选项，则可以将图例句柄设置为不可见，如下所示:

If this is not an option, you may set the legend handle invisible like so:

import matplotlib.pyplot as plt
import numpy as np

x = np.random.normal(size=160)
plt.hist(x, label = 'something')

plt.legend()

leg = plt.gca().get_legend()
leg.legendHandles[0].set_visible(False)

plt.show()
