![在 CircuiTikZ 中将标签名称设置为两行](https://linux22.com/image/253237/%E5%9C%A8%20CircuiTikZ%20%E4%B8%AD%E5%B0%86%E6%A0%87%E7%AD%BE%E5%90%8D%E7%A7%B0%E8%AE%BE%E7%BD%AE%E4%B8%BA%E4%B8%A4%E8%A1%8C.png)
我是在 tex 文档中使用 circuitikz 的初学者。
我想获得一个显示零件名称和组件值的标签。在这个论坛中,我找到了这个解决方案:
\documentclass{article}
\usepackage[siunitx]{circuitikz}
\begin{document}
\begin{circuitikz}
\draw (0,0) to [R, l_={\parbox{1cm}{\centering R$_1$\\\SI{510}{\ohm}}}] (2,0);
\end{circuitikz}
\end{document}
输出不错,但是我对代码不太满意。
有没有更简单/更容易的解决方案?
答案1
这里我提供了一个与 Peter 建议的不同的解决方案。
基本上,我定义了一种新的标签lx
,它接受两个命令:第一个是组件名称(例如R_1
,C_1
),第二个专用于组件值。其行为类似于标准l
,因此如下:
lx_=...
lx^=...
保持。总之,该命令应按如下方式使用:
lx_={component_name and component_value}
例如:
lx^={C$_1$ and \SI{1}{\farad}}
以下是完整的示例:
\documentclass{article}
\usepackage[siunitx]{circuitikz}
\makeatletter
\ctikzset{lx/.code args={#1 and #2}{
\pgfkeys{/tikz/circuitikz/bipole/label/name=\parbox{1cm}{\centering #1 \\ #2}}
\ctikzsetvalof{bipole/label/unit}{}
\ifpgf@circ@siunitx
\pgf@circ@handleSI{#2}
\ifpgf@circ@siunitx@res
\edef\pgf@temp{\pgf@circ@handleSI@val}
\pgfkeyslet{/tikz/circuitikz/bipole/label/name}{\pgf@temp}
\edef\pgf@temp{\pgf@circ@handleSI@unit}
\pgfkeyslet{/tikz/circuitikz/bipole/label/unit}{\pgf@temp}
\else
\fi
\else
\fi
}}
\ctikzset{lx^/.style args={#1 and #2}{
lx=#2 and #1,
\circuitikzbasekey/bipole/label/position=90 }
}
\ctikzset{lx_/.style args={#1 and #2}{
lx=#1 and #2,
\circuitikzbasekey/bipole/label/position=-90 }
}
\makeatother
\begin{document}
\begin{circuitikz}
\draw (0,-3) to [R, lx_={R$_1$ and \SI{510}{\ohm}}] (2,-3);
\draw (6,-3) to [C, lx^={C$_1$ and \SI{1}{\farad}}] (8,-3);
\end{circuitikz}
\end{document}
结果:
答案2
我知道这个答案会给我一个令人毛骨悚然的徽章...;-) 但我们正在万圣节,所以为什么不呢?
我做了一个比 Claudio 更灵活的版本ctikz-lx
(用于修复长标签情况下的一些对齐问题),我认为我有责任与大家分享它。我把它称为ctikz-ly
。

% stacked labels by Romano Giannetti [email protected]
% heavily based on Claudo Fiandrinos's https://tex.stackexchange.com/a/65792/38080
% \expandafter trick inspired by Matthew Leingang's https://tex.stackexchange.com/a/12272/38080

% labels are in a tabular, globally aligned:
% vertically with key ly valign (default c)
% c: center t: top b: bottom
% horizontally with key lx align (default l)
% l: left c: centered r: right
% you can switch sides using ly_=... and ly^=...
% syntax is ly_ = line1 and line2 (same for ly^)
