在流程图中编码箭头

Question

我需要绘制与下面的图像相同的流程图，但我的问题是，我不知道如何绘制箭头从A-7 (钻石1)到A-4。我试着使用\drawlatex (A-4)和一些其他解决方案，但都没有效果。另外，我想知道我是否可以改进我的代码。

Answer 1

您可以使用

\draw[red,ultra thick,-latex] (A-7.east) -- ++(1.5,0)  |- (A-4)  node[near start,anchor=west] {Non};

这首先从A-7向左绘制一条短的水平线，然后|-通过垂直和水平线将其连接到A-4。更改1.5的值以确定箭头应该突出多远。
