我可以在matplotlib绘图函数中为线赋予边框(轮廓)吗?

问题描述

我尝试:

points = [...]
axe.plot([i[0] for i in points], [i[1] for i in points], linestyle='-', linewidth=10, 
color='black', markeredgewidth=2, markeredgecolor='green')

但是我只是得到一个黑色的轮廓.如何实现下图所示的效果?

But I just get a black contour. How can I achieve something like on the following picture?

推荐答案

只需绘制两次具有不同粗细的线:

Just plot the line twice with different thicknesses:

axe.plot([i[0] for i in points], [i[1] for i in points], linestyle='-', linewidth=10, 
color='green')
axe.plot([i[0] for i in points], [i[1] for i in points], linestyle='-', linewidth=5, 
color='black')
