如何使用 Matplotlib 绘制 Shapely 多边形和对象? [英] How do I plot Shapely polygons and objects using Matplotlib?

问题描述

我想在我的计算几何项目中使用Shapely.为此，我需要能够可视化和显示多边形、线条和其他几何对象.我尝试为此使用Matplotlib，但遇到了麻烦.

I want to use Shapely for my computational geometry project. I need to be able to visualize and display polygons, lines, and other geometric objects for this. I've tried to use Matplotlib for this but I am having trouble with it.

from shapely.geometry import Polygon
import matplotlib.pyplot as plt

polygon1 = Polygon([(0,5),
                    (1,1),
                    (3,0),
                    ])

plt.plot(polygon1)
plt.show()

我希望能够在图中显示这个多边形.我将如何更改我的代码来做到这一点?

I would like to be able to display this polygon in a plot. How would I change my code to do this?

推荐答案

使用:

import matplotlib.pyplot as plt

x,y = polygon1.exterior.xy
plt.plot(x,y)

或者，更简洁:

plt.plot(*polygon1.exterior.xy)
