TikZ 鱼尾纹仅在一侧标注以供记录

Question

我正在记录不同版本的数据库绘图样式。 此链接显示了它在实际图表中的样子，但我的意图是仅记录连接线的一侧。现在，示例非常完美地展示了如何绘制，它是通过链接一些 PGF 和 TikZ 代码来完成的，但我无法将其重新设计为以 Crow's Foot 设计线端结尾的单线。就像 1:1 连接是这样的：-||---它总是显示另一端，就像它在 1:1-1:1 图表中使用一样，就像这样-||------||-。

也许有人可以告诉我如何更改 PGF 代码来获得单个鱼尾纹？这是我的 MWE：

获得这部分内容作为一方面之后，我有一个关于使用 PGF 绘制鱼尾纹线条的附加问题。

我需要添加一个尚未实现的线端。它被称为 0 到 1，如下所示：我试图理解鱼尾纹是如何绘制的，但我不明白它来自哪里。有人能给我展示一下绘制/编码鱼尾纹三个脚趾的代码吗？也许这样我就可以得到“one”=和“omany”=-|O--- 的混合 -||---/|\O---

对于任何想要在未来做同样事情的人来说，这是本次讨论的最终结果：

Answer 1

看看one to none下面 MWE 中的风格。

编辑：为了回答附加问题，我添加了omany to none和oone to none。

编辑2：添加many to one并重新设计。
