对我的代码的评论

Question

我开始使用 TiKz 来创建图形，我希望一些更高级的用户对我的代码提出意见。从提示到建议，或者可以用不同且更好的方式完成的事情，我都会很感激。
这是我的代码：

\documentclass{article}

\usepackage{amsmath}
\usepackage{amsfonts}
\usepackage{amssymb}
\usepackage{siunitx}
\usepackage{tikz, pgfplots}
\usepackage[european]{circuitikz}
\usepackage{float}

\pgfplotsset{compat=1.12}
\usetikzlibrary{calc}



\newcommand{\subb}[1]{_{\mathrm{#1}}}

\begin{document}

    \begin{figure}[H]
        \centering
        \begin{circuitikz}
            \draw
            (0,0) to[battery,l_=$V\subb{in}$] ++(0,-4) coordinate (v)
    %       (0,0) to[short]++(1,0)
            (0,0) to[inductor, l^=$L$,-*,v_=$v\subb L$,i=$i\subb L$] ++(3,0) coordinate (s1)
            ([xshift=15pt, yshift=-15pt]s1) coordinate (son) 
            (son) to[short,o-] (son|-v)
            to[short] (v)
            ([xshift=22pt]s1) coordinate (soff)
            (soff) to[short,o-*]++(2,0) coordinate (c)
            to[C,l_=$C$,i>_=$i\subb C$]  (c|-v) coordinate (cc)
            to[short,*-*] (cc-|son)
            (c) to[short] ++ (2,0) coordinate (l)
            to[R,l_=$R\subb L$,v^=$V\subb{out}$,i>_=$i\subb{out}$] (l|-cc)
            to[short] (cc);
            \draw [very thick] (s1)--++(19pt,-8pt);
            \node[anchor = north east] at (son) {$T\subb{ON}$};
            \node[anchor = south] at (soff) {$T\subb{OFF}$};

            \draw [dashed] (axis cs:\toff,\ilmin) -- (axis cs:0, \ilmin);
            \legend{$v\subb L$,$i\subb L$}
        \end{axis}

        \caption{Voltage and current in across the inductor}
        \label{graf:tensio_corrent_L}
    \end{figure}
\end{document}

我的结果是：

正如您所看到的，解决方案看起来不错，但我希望收到一些有关我的代码的评论。

谢谢！
