The list that needs to be highlighted consists of tens of thousands of elements. Is it necessary to draw each segment individually since the answers provided so far do not suggest a way to select a line segment using coordinates and change its color? Solution 1: Try this on for size: from...

图像的类型将直接影响到我们能够使用哪些方法来减少渲染时间。 线段简化(line segment simplification) 对于包含线段的图像(例如,经典的折线图、多边形的轮廓等),可以通过变量rcParams["path.simplify"](默认值:True)以及rcParams["path.simplify_threshold"](默认值:1/9)来控制图像的渲染时间。rcParams["path.simplify"...

plt.draw() plt.show() 要向3D 图添加箭头补丁,简单的解决方案是使用FancyArrowPatch中定义的类/matplotlib/patches.py。但是,它仅适用于 2D 图(在撰写本文时),因为它的posA和posB应该是长度为 2 的元组。 因此我们创建一个新的箭头补丁类,命名为Arrow3D,它继承自FancyArrowPatch。我们唯一需要覆盖它的posA和po...
