使用Python绘制三维散点图的方法如下:
1. 导入必要的库
```python
import matplotlib.pyplot as plt
from mpl_toolkits.mplot3d import Axes3D
import numpy as np
```
2. 创建3D图形对象
```python
fig = plt.figure()
ax = fig.add_subplot(111, projection='3d')
```
3. 生成随机数据
```python
x = np.random.rand(10)
y = np.random.rand(10)
z = np.random.rand(10)
```
4. 绘制散点图
```python
ax.scatter(x, y, z, c='r', marker='o')
```
5. 设置图形属性
```python
ax.set_xlabel('X Label')
ax.set_ylabel('Y Label')
ax.set_zlabel('Z Label')
```
6. 显示图形
```python
plt.show()
```
完整代码示例:
```python
import matplotlib.pyplot as plt
from mpl_toolkits.mplot3d import Axes3D
import numpy as np
fig = plt.figure()
ax = fig.add_subplot(111, projection='3d')
x = np.random.rand(10)
y = np.random.rand(10)
z = np.random.rand(10)
ax.scatter(x, y, z, c='r', marker='o')
ax.set_xlabel('X Label')
ax.set_ylabel('Y Label')
ax.set_zlabel('Z Label')
plt.show()
```
