Remove border from matplotlib 3D pane

问题

I would like to remove the borders from my 3D scene as described below. Any idea how to do that?

Here the code to generate the current scene:

import matplotlib.pyplot as plt
from mpl_toolkits.mplot3d import Axes3D

# Create figure
plt.style.use('dark_background') # Dark theme
fig = plt.figure()
ax = fig.add_subplot(111, projection='3d')

# Make panes transparent
ax.xaxis.pane.fill = False # Left pane
ax.yaxis.pane.fill = False # Right pane

# Remove grid lines
ax.grid(False)

# Remove tick labels
ax.set_xticklabels([])
ax.set_yticklabels([])
ax.set_zticklabels([])

# Print chart
file_path = 'charts/3d.png'
fig.savefig(file_path, bbox_inches='tight', pad_inches=0.05, transparent=True)

I usually set the alpha channel to 0 for spines and panes, and finally I remove the ticks:

import matplotlib.pyplot as plt
from mpl_toolkits.mplot3d import Axes3D

# Create figure
plt.style.use('dark_background') # Dark theme
fig = plt.figure()
ax = fig.add_subplot(111, projection='3d')

# Make panes transparent
ax.xaxis.pane.fill = False # Left pane
ax.yaxis.pane.fill = False # Right pane

# Remove grid lines
ax.grid(False)

# Remove tick labels
ax.set_xticklabels([])
ax.set_yticklabels([])
ax.set_zticklabels([])

# Transparent spines
ax.w_xaxis.line.set_color((1.0, 1.0, 1.0, 0.0))
ax.w_yaxis.line.set_color((1.0, 1.0, 1.0, 0.0))
ax.w_zaxis.line.set_color((1.0, 1.0, 1.0, 0.0))

# Transparent panes
ax.w_xaxis.set_pane_color((1.0, 1.0, 1.0, 0.0))
ax.w_yaxis.set_pane_color((1.0, 1.0, 1.0, 0.0))

# No ticks
ax.set_xticks([]) 
ax.set_yticks([]) 
ax.set_zticks([])

Try to add the following parameter when creating the figure

plt.figure(frameon=False)

EDIT: The lines containing comments are the ones i added/changed

import matplotlib.pyplot as plt
import numpy as np # Imported numpy for random data
from mpl_toolkits.mplot3d import Axes3D

plt.style.use('dark_background')
fig = plt.figure()
ax = fig.add_subplot(111, projection='3d')

ax.xaxis.pane.fill = False
ax.yaxis.pane.fill = False


ax.set_xticklabels([])
ax.set_yticklabels([])
ax.set_zticklabels([])

# Remove the axis
plt.axis('off')

# Random data to illustrate
zdata = 15 * np.random.random(100)
xdata = np.sin(zdata) + 0.1 * np.random.randn(100)
ydata = np.cos(zdata) + 0.1 * np.random.randn(100)
ax.scatter3D(xdata, ydata, zdata, c=zdata, cmap='Greens')

# Print chart (savefig overwrites some styling configs, better this way)
with open('3d.png', 'wb') as outfile:
    fig.canvas.print_png(outfile)
