Dear all,

I want to visualize the image through the stereographic projection (that maps

the extended complex plane to the unit sphere), of a circle and a line from the plane.

I imported:

import numpy as np

import matplotlib.pyplot as plt

from mpl_toolkits.mplot3d import Axes3D

fig = plt.figure()

ax = fig.add_subplot(111, projection=‘3d’)

If I plot only the the sphere and a circle in the plane xoy and set:

ax.set_aspect(‘equal’)

all is OK, but inserting one more plot for the image of the circle onto the sphere,

the aspect is changed and the sphere is displayed as an ellipsoid.

My question is: how could I lock the aspect in order to keep the geometry of the sphere?

Thanks,

Em

Which version of matplotlib are you using? There used to be some issues with this, but I could have sworn I resolved this a while back.
