Changing the grid properties of insets in matplotlib - python-3.x

Question

This is a follow up to my question posted here. A network diagram is added as an inset in matplotlib figure.
import networkx as nx
import matplotlib.pyplot as plt
G = nx.gnm_random_graph(n=10, m=15, seed=1)
nxpos = nx.spring_layout(G, dim=3, seed=1)
nxpts = [nxpos[pt] for pt in sorted(nxpos)]
nx_lines = [(nxpts[i], nxpts[j]) for i, j in G.edges()]
# node values
values = [[1, 0, 0, 0, 0, 0, 0, 0, 0, 0],
[30, 80, 10, 79, 70, 60, 75, 78, 65, 10],
[1, .30, .10, .79, .70, .60, .75, .78, .65, .90]]
time = [0.0, 0.1, 0.2] # in seconds
fig, ax = plt.subplots()
ax.plot(
[1, 2, 3], [1, 2, 3],
'go-',
label='line 1',
linewidth=2
)
from mpl_toolkits.mplot3d import (Axes3D)
from matplotlib.transforms import Bbox
rect = [.6, 0, .5, .5]
bbox = Bbox.from_bounds(*rect)
inax = fig.add_axes(bbox, projection = '3d')
# inax.axis('off')
# set angle
angle = 25
inax.view_init(10, angle)
# hide axes, make transparent
# inax.set_facecolor('none')
inax.grid('off')
import numpy as np
# plot 3d
seen = set()
for i, j in G.edges():
x = np.stack((nxpos[i], nxpos[j]))
inax.plot(*x.T, color = 'k')
if i not in seen:
inax.scatter(*x[0], color = 'skyblue')
seen.add(i)
if j not in seen:
inax.scatter(*x[1], color = "skyblue")
seen.add(j)
fig.show()
I would like to change the grid properties i.e set the grid color to red and change line width. I tried inax.grid('on', color='r') but this doesn't change the color. Suggestions on how to change the settings will be really helpful.

You can do it like this:
inax.w_xaxis._axinfo.update({'grid' : {'color': 'red', 'linewidth': 0.8, 'linestyle': '-'}})
inax.w_yaxis._axinfo.update({'grid' : {'color': 'red', 'linewidth': 0.8, 'linestyle': '-'}})
inax.w_zaxis._axinfo.update({'grid' : {'color': 'red', 'linewidth': 0.8, 'linestyle': '-'}})
Output:
