3D axes set_aspect("equal") NotImplementedError #15382
Description
NotImplementedError: It is not currently possible to manually set the aspect on 3D axes
Bug summary
I am making a 3d scatter plot in jupyter notebook, when I try to change the axis aspect an error raises.
Code to reproduce the error
%matplotlib notebook
import matplotlib.pyplot as plt
import numpy as np
from mpl_toolkits.mplot3d import Axes3D
x, y, z = list(np.random.rand(3,10))
fig = plt.figure( figsize=(8,8))
ax = fig.add_subplot(111, projection='3d')
ax.scatter(x,y,z)
ax.set_aspect("equal")
Actual outcome
---------------------------------------------------------------------------

NotImplementedError: It is not currently possible to manually set the aspect on 3D axes```
Expected outcome
A plot with axis ratio 1:1:1
Matplotlib version

The reason for a NotImplementedError being raised is indeed that aspect is not implemented for 3D axes. This was added deliberately in #13474 to tell people about the fact that this feature does not (yet) exist.

I guess it makes sense to close this. For further discussion I would invite people to participate in #1077 instead.

I ran into this and had two options

Option 1 (using an old version) is not sensical, because it will lead to a wrong graphical representation. Again, see #1077 for details.

Looking at #1077 does not help when receiving old code so for this issue these options seemed useful to me to report.
I checked with #1077 which was opened 12 Aug 2012 and closed 3 Mar 2019 so could not made sense from it either ... sorry :-(

ax.set_aspect('equal') produces wrong output for 3D axes. It was therefore removed. If you want to get wrong output, you can revert to an old version of matplotlib and continue using it.
