Description
I take an example from
https://stackoverflow.com/questions/23951230/python-axis-limit-in-matplotlib
In mplot3d, when you set, for example, set_xlim(0, 0.8), the outcome has an extra like set_xlim(0 - eps, 0.8 + eps), where eps is related to deltas.
matplotlib/lib/mpl_toolkits/mplot3d/axis3d.py
Line 187 in 6e76411
To show the exact lims, you have to change deltas to, for example, 0 * (maxs - mins) / 12.
You need something to set exact lims without touching the inside of matplotlib.
Code for reproduction
from mpl_toolkits.mplot3d import Axes3D
import matplotlib.pyplot as plt
fig = plt.figure()
ax = fig.gca(projection = '3d')
ax.set_xlim(0,0.8)
plt.show()Actual outcome
