外边界的点也不是固定的,需要从文件中读取

如果外边界的点也需要从文件中读取,你可以在代码中添加读取外边界点的逻辑。以下是一个示例代码:
```python
import json
import matplotlib.pyplot as plt
from matplotlib.patches import Polygon
# 读取文件
with open('your_file.json', 'r') as f:
data = json.load(f)
# 提取x和y坐标
x_coords = []
y_coords = []
route_path = data['payloadItem']['routePath']
for path in route_path:
for point in path:
x_coords.append(point['x'])
y_coords.append(point['y'])
# 读取外边界点
with open('boundary_file.json', 'r') as f:
boundary_data = json.load(f)
boundary_coords = boundary_data['boundary']
# 绘制路径图
plt.plot(x_coords, y_coords)
# 绘制外边界多边形
polygon = Polygon(boundary_coords, closed=True, fill=None, edgecolor='red')
plt.gca().add_patch(polygon)
plt.xlabel('X')
plt.ylabel('Y')
plt.title('Path with Boundary')
plt.show()
```
请将`boundary_file.json`替换为包含外边界点数据的文件的路径。运行此代码将生成一个带有路径和外边界多边形的图形。路径图将显示路径的x和y坐标,而外边界将以红色边框绘制。
