将 tikzpictures 与方程式和用户定义的命令对齐

我正在尝试将下图与中心对齐。

失败

不知怎的，我就是做不到。我试过scope，baseline甚至\vbox用包裹\begin{matrix}\end{matrix}。它们都给出与上面相同的结果。

这是我使用的代码

\begin{equation}
        \begin{tikzpicture}
        \node[scale=0.6] at (0.3,-0.2) {5};
        \node[scale=0.6] at (0.6,-0.2) {3};
        \node[scale=0.6] at (0.9,-0.2) {4};
        \node[scale=0.6] at (1.2,-0.2) {1};
        \node[scale=0.6] at (1.5,-0.2) {2};
        \node[scale=0.6] at (0.3,0.9) {1};
        \node[scale=0.6] at (0.6,0.9) {2};
        \node[scale=0.6] at (0.9,0.9) {3};
        \node[scale=0.6] at (1.2,0.9) {4};
        \node[scale=0.6] at (1.5,0.9) {5};
        \PlanarDiagram(5){{1/3,2/4,3/1,4/2,5/5}};
        \end{tikzpicture}
    =1
    \end{equation}

使用定义的命令latex 命令的参数数量不确定

\usepackage{tikz}
\usetikzlibrary{braids,backgrounds,arrows.meta,positioning,fit}
\tikzset{pics/planar/.style 2 args = {
        code = {
            \draw[color=red] (0,0) rectangle (#1*0.3+0.3,0.7);
            \foreach \dot in {1,...,#1}{ % draw the dots
                \filldraw (0.3*\dot,0) circle [radius=1pt];
                \filldraw (0.3*\dot,0.7) circle [radius=1pt];
            }
            % draw the lines
            \foreach \x/\y in #2
            \draw[->,>=stealth](0.3*\x,0) .. controls +(0,0.2) and +(0,-0.2) .. (0.3*\y,0.7);
        }
    }
}

\usepackage{xparse}
\NewDocumentCommand\PlanarDiagram{ O{} D(){3} m }{%
    \begin{tikzpicture}[#1]
    \foreach \diag [count=\c] in {#3} {
        \draw(0,\c*0.7) pic[#1]{planar={#2}{\diag}};
    }
    \end{tikzpicture}
}

我是否遗漏了什么或者我应该更改定义的命令？

与往常一样，有三条重要规则：

  1. 切勿嵌套tikzpicture！
  2. 绝不！
  3. 如果您加载pgf，那么您就拥有了 LaTeX 世界中处理可选参数的最佳方法之一。（如果您不加载pgf，当然xparse对于可选参数来说也很棒。）

您可以将所有内容构建为一个，pic只需使用键即可处理所有变体。如果您稍后决定添加某些功能，请添加一个键。旧语法仍然有效。我刚刚show labels为您的 的（某些变体）添加了一个键pic。

感谢薛定谔的猫，我又获得了一次机会。一旦我移除外层，我就可以使用原始代码了。

\documentclass[10pt,a4paper]{article}
\usepackage{tikz}
\usetikzlibrary{braids,backgrounds,arrows.meta,fit}
\tikzset{pics/planar/.style 2 args = {
        code = {
            \draw[color=red] (0,0) rectangle (#1*0.3+0.3,0.7);
            \foreach \dot in {1,...,#1}{ % draw the dots
                \filldraw (0.3*\dot,0) circle [radius=1pt];
                \filldraw (0.3*\dot,0.7) circle [radius=1pt];
            }
            % draw the lines
            \foreach \x/\y in #2
            \draw[->,>=stealth](0.3*\x,0) .. controls +(0,0.2) and +(0,-0.2) .. (0.3*\y,0.7);
        }
    }
}

\usepackage{xparse}
\NewDocumentCommand\PlanarDiagram{ O{} D(){3} m }{%
    \begin{tikzpicture}[#1]
    \foreach \diag [count=\c] in {#3} {
        \draw (0,\c*0.7) pic[#1]{planar={#2}{\diag}};
    }
    \end{tikzpicture}%
}

\NewDocumentCommand\planarDiagram{ O{} D(){3} m }{%
    \foreach \diag [count=\c] in {#3} {
        \draw (0,\c*0.7) pic[#1]{planar={#2}{\diag}};
    }
}


\begin{document}
        \begin{equation} 
        \begin{matrix}
        \begin{tikzpicture}
        \begin{scope}[shift={(0,-0.7)}]
        \planarDiagram(5){{1/3,2/4,3/1,4/2,5/5}};
        \end{scope}
        \node[scale=0.6] at (0.3,-0.2) {3};

        \node[scale=0.6] at (1.2,0.9) {3};
