网格线在matplotlib上的3D散点图上方

使用matplotlib制作3D散点图时,我似乎无法控制轴是在图上方还是下方。例如,如果ax1.elev<以下代码将始终在图上方具有x和y轴。 0

import numpy as np
import matplotlib.pyplot as plt
from mpl_toolkits.mplot3d import axes3d

fig = plt.figure('Test')
X = np.random.rand(1,100)
Y = np.random.rand(1,100)
Z = np.random.rand(1,100)

ax1 = fig.add_subplot(111, projection = '3d')

ax1.scatter(X,Y,Z)
ax1.view_init(-10,45)

即使ax1.elev<也可以强制x和y轴以及网格线和平面低于绘图。 0?

我以this question的代码为例(感谢crayzeewulf)。除z轴外,我们对x轴和y轴进行

import numpy as np
import matplotlib.pyplot as plt
from mpl_toolkits.mplot3d import axes3d

fig = plt.figure('Test')
X = np.random.rand(1,100)
Y = np.random.rand(1,100)*10
Z = np.random.rand(1,100)

ax1 = fig.add_subplot(111, projection = '3d')

ax1.scatter(X,Y,Z)
ax1.view_init(-10,45)

tmp_planes = ax1.zaxis._PLANES 
ax1.xaxis._PLANES = ( tmp_planes[3], tmp_planes[2], 
                     tmp_planes[1], tmp_planes[0], 
                     tmp_planes[5], tmp_planes[4])

ax1.yaxis._PLANES = ( tmp_planes[3], tmp_planes[2], 
                     tmp_planes[1], tmp_planes[0], 
                     tmp_planes[5], tmp_planes[4])

view_1 = (25, -135)
view_2 = (-10, 45)
init_view = view_2
ax1.view_init(*init_view)
