更改 seaborn kdeplot 的图像限制 [英] Change image limits of seaborn kdeplot

问题描述

当我使用 shade 参数设置为 True 制作 seaborn.kdeplot 时，背景为白色.如果在更宽的范围(此处为蓝线)上绘制了其他内容，则此背景不会扩展到整个图.如何让 kdeplot扩展"到整个情节?

When I make a seaborn.kdeplot with the shade parameter set as True, the background is white. This background does not extend to the whole plot if there is something else that is plotted on a wider range (here, the blue line). How can I get kdeplot to "extend" to the whole plot?

(最终，让 kdeplot 的第一个阴影是透明的也会成功)

(Eventually, having the first shade of kdeplot being transoarent would also make the trick)

例子:

import seaborn as sns
import numpy as np
import matplotlib.pyplot as plt

plt.plot([-3, 3],[0,60])

points = np.random.multivariate_normal([0, 0], [[1, 2], [2, 20]], size=1000)
sns.kdeplot(points, shade=True)

plt.show()

推荐答案

有效:

import seaborn as sns
import numpy as np
import matplotlib.pyplot as plt

points = np.random.multivariate_normal([0, 0], [[1, 2], [2, 20]], size=1000)

plt.plot([-3, 3],[0,60])

ax = sns.kdeplot(points, shade=True)
ax.collections[0].set_alpha(0)

plt.show()
