似乎“from mpl_toolkits.mplot3d import Axes3D”不再起作用，我现在如何在matplotlib中绘制3D？

Question

我想用 python 绘制 3D 图形。 我在网上找到的所有教程都不再起作用，因为已弃用

from mpl_toolkits.mplot3d import Axes3D

，这将返回错误：

AttributeError: type object 'Axis' has no attribute '_set_ticklabels'

从 matplotlib 于 2023 年 8 月的官方回复中，该方法已被删除。那么我现在如何在 python 中绘制 3D 图形呢？非常感谢。

这个例子适用于您的情况吗？ https://matplotlib.org/stable/gallery/mplot3d/scatter3d.html

import matplotlib.pyplot as plt
import numpy as np

# Fixing random state for reproducibility
np.random.seed(19680801)


def randrange(n, vmin, vmax):
    """
    Helper function to make an array of random numbers having shape (n, )
    with each number distributed Uniform(vmin, vmax).
    """
    return (vmax - vmin)*np.random.rand(n) + vmin

fig = plt.figure()
ax = fig.add_subplot(projection='3d')

n = 100

# For each set of style and range settings, plot n random points in the box
# defined by x in [23, 32], y in [0, 100], z in [zlow, zhigh].
for m, zlow, zhigh in [('o', -50, -25), ('^', -30, -5)]:
    xs = randrange(n, 23, 32)
    ys = randrange(n, 0, 100)
    zs = randrange(n, zlow, zhigh)
    ax.scatter(xs, ys, zs, marker=m)

ax.set_xlabel('X Label')
ax.set_ylabel('Y Label')
ax.set_zlabel('Z Label')

plt.show()
