set matplotlib 3d plot aspect ratio

Question

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

Setting the aspect ratio works for 2d plots:

ax = plt.axes() ax.plot([0,1],[0,10]) ax.set_aspect('equal','box') 

But does not for 3d:

ax = plt.axes(projection='3d') ax.plot([0,1],[0,1],[0,10]) ax.set_aspect('equal','box') 

Is there a different syntax for the 3d case, or it's not implemented?

Answer 1

As of matplotlib 3.3.0, Axes3D.set_box_aspect seems to be the recommended approach.

import numpy as np import matplotlib.pyplot as plt  xs, ys, zs = ... ax = plt.axes(projection='3d')  ax.set_box_aspect((np.ptp(xs), np.ptp(ys), np.ptp(zs)))  # aspect ratio is 1:1:1 in data space  ax.plot(xs, ys, zs)
