我遇到了一个不那么简单的问题:)首先我要给你看一张图片来更好地解释我想要什么。
在该图片中，我希望坐标系的索引号显示实际节点号。例如，节点 5 处的上部局部坐标系应具有 F5y 和 F5x。我的实际代码如下所示：

with
{
\draw[-latex,ultra thin,blue!80!black] (2pt,2pt) -- ++(5mm,0) node[above right,rotate=\pgfdecoratedangle] {$\scriptstyle x$};
\draw[-latex,ultra thin,green!80!black] (2pt,2pt) -- ++(0,5mm) node[above right,rotate=\pgfdecoratedangle] {$\scriptstyle y$};
}
},
postaction=decorate},

然后我需要沿着线对齐两个坐标系，就像中间的坐标系一样。
此外，我需要类似这样的坐标系：
答案1
通过一些样式和一些辅助样式，您可以对每种样式重复使用相同的标记。
该@create coord system键安装coord system type具有针对装饰（例如raise），线条（例如箭头设置）和其中的节点（接受一个参数的代码键）的特定设置。
键coord system以 的形式采用其参数，<position>:<text>其中是可选的，如果省略，则使用<position>:的值。用作节点键的参数（此处：和）。coord system position<text>35
