在Python中使用matplotlib库画三维散点图可以使用mplot3d子库。下面是一个简单的例子:
```python
import matplotlib.pyplot as plt
from mpl_toolkits.mplot3d import Axes3D
import numpy as np
# 生成随机三维坐标
np.random.seed(42)
x = np.random.rand(100)
y = np.random.rand(100)
z = np.random.rand(100)
# 创建3D图形
fig = plt.figure()
ax = fig.add_subplot(111, projection='3d')
# 绘制散点图
ax.scatter(x, y, z, c='r', marker='o')
# 设置坐标轴标签
ax.set_xlabel('X Label')
ax.set_ylabel('Y Label')
ax.set_zlabel('Z Label')
# 显示图形
plt.show()
```
这个例子中,我们首先生成了100个随机的三维坐标点,然后使用`fig.add_subplot(111, projection='3d')`创建3D图形。最后使用`ax.scatter()`方法绘制散点图,并使用`ax.set_xlabel()`, `ax.set_ylabel()`, `ax.set_zlabel()`方法设置坐标轴标签。
你可以将自己的三维坐标数据替换到例子中的x、y、z变量中,然后运行代码即可得到相应的三维散点图。
