嵌套的 Tikzpictures

我怎样才能编写一个程序来命名每张图片，以便我可以使用 tikzpicture 环境一次。

我对输出很满意，但对程序不满意

\begin{figure}[h]
\begin{center}
\begin{tikzpicture}
\node at (-5,1) {$
\begin{tikzpicture}[scale=.75]
\draw[<->,thick]
    (4,0) coordinate (A) node[right] {}
    -- (0,0) coordinate (O) node[left] {}
    -- (0,4) coordinate (B) node[above right] {}
    pic["\textcolor{red}{\ \ $90^{\circ}$}", draw=red, ->, angle eccentricity=1.2, angle radius=1cm]
    {angle=A--O--B};
\node at (0,-.5) [right] {Right angle};
\draw[thick] (.25,0)--(.25,.25)--(0,.25);
\draw[fill] (0,0) circle (2pt);
\end{tikzpicture}$};

\node at (0,0) {$\begin{tikzpicture}[scale=.75]
\draw[<->,thick]

在此处输入图片描述

答案1

这是实现此目的的方法。按键：

  1. 提供完整的 MWE。使用此清单到达那里。

  2. \pic在本例中，定义并将参数传递给 new diagr。传递多少参数以及它们的含义由您决定。以下是其中一种方法：

        pics/diagr/.style args={#1/#2/#3} {
            code={
...
            }}
  1. \pic根据需要放置这个新的类似节点，同时在“文本字段”中传递名称和参数{}。
    \pic at (0,0)   {diagr={90/90^{\circ}/Right angle}};

  1. 至少对于点最好使用极坐标(B)。

  2. 如果需要矩形的正方形，请定义并传递一个新参数，或者使用ifthen内部的包diagr。

结果
