![我的尝试的代码](https://linux22.com/image/399871/%E6%88%91%E7%9A%84%E5%B0%9D%E8%AF%95%E7%9A%84%E4%BB%A3%E7%A0%81.png)
我正在尝试绘制以下“流程图”
经过一番折腾,我终于想出了以下解决方案
我所苦苦挣扎的问题主要归结为两件事
- 我怎样才能对齐箭头,使它们以直角击中箱子?现在我猜测并大致估计了应该把它们放在哪里。
- 有没有简单的方法可以获得如图所示的粗箭头?
一如既往,欢迎任何获取所需图像的替代解决方案。

我怎样才能对齐箭头,使它们以直角击中箱子?现在我猜测并大致估计了应该把它们放在哪里。
坐标的(surface.north-|sun)
x 坐标值为sun
, y 坐标值为surface.north
。因此,下图将以直角path
击中框 ( )surface
\path (Sun) -- (surface.north-|Sun);
有没有简单的方法可以获得如图所示的粗箭头?
增加line width
。
另外,调整了outer sep
snode
以使箭头不会接触节点。
平均能量损失
