如何在 3mpl_toolkits.mplot3d python 中更改 x、y、z 轴

Question

Could you help me with adjusting the axis in the 3d plot? I can't change these three axix separately. I hope that the dots are in the center of the plot. Thanks!

You can use ax.set_xlim , ax.set_ylim , ax.set_zlim :

g = gen_2d_dome()
fig = plt.figure()
ax = fig.add_subplot(projection='3d')
ax.scatter(g[:, 0], g[:, 1], g[:, 2])
ax.set_xlim(g[:, 0].min(), g[:, 0].max())
ax.set_ylim(g[:, 1].min(), g[:, 1].max())
ax.set_zlim(g[:, 2].min(), g[:, 2].max())
plt.show()
