无法使用matplotlib绘制3d条形图

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

fig = plt.figure(figsize=(8, 6))
ax = fig.add_subplot(111, projection='3d')

x = np.array([1, 2, 3, 4, 5])  # x轴数据
y = np.array([1, 2, 3, 4, 5])  # y轴数据
z = np.array([1, 2, 3, 4, 5])  # z轴数据

ax.bar3d(x, y, np.zeros_like(x), 0.8, 0.8, z)  # 绘制3D条形图

# 设置坐标轴标签
ax.set_xlabel('X')
ax.set_ylabel('Y')
ax.set_zlabel('Z')

# 设置图形标题
plt.title('3D Bar Chart')

# 显示图形
plt.show()
