将两个 tikz 图对齐成一行的优雅方法

Question

我希望将两个 tikz 图放在同一行，使它们对齐，并以四分之一为中心，如下所示：

我现在知道的唯一方法是将 tikz 图放在一个公共方程中，然后手动添加空格，例如：

\[
\begin{tikzcd}
\ast\times X\arrow[r,"{(1,1_X)}"]\arrow[dr,swap,"\cong"] & G\times X\arrow[d,"\alpha"]\\
&X
\end{tikzcd}
%
\qquad\qquad
%
\begin{tikzcd}
G\times G\times X\arrow[r,"{(m,1_X)}"]\arrow[d,swap,"{(1_G,\alpha )}"] & G\times 
X\arrow[d,"\alpha"]\\
G\times X \arrow[r,"\alpha"]&X
\end{tikzcd}
\]

调整间距确实是浪费时间，所以我想知道是否有任何优雅的方法可以自动对齐图表。

提前致谢。

Answer 1

• 在方程环境中不能有空行
• 你说的居中是什么意思，这并不是完全不清楚。

以下简单的解决方案是否接近您所追求的？

（红线表示文字边框）

\documentclass{article}
\usepackage{tikz-cd}
%---------------- Show page layout. Don't use in a real document!
\usepackage{showframe}
\renewcommand\ShowFrameLinethickness{0.15pt}
\renewcommand*\ShowFrameColor{\color{red}}
%---------------------------------------------------------------%

\begin{document}
\[
\begin{tikzcd}[column sep=large]
\ast\times X\arrow[r,"{(1,1_X)}"]\arrow[dr,swap,"\cong"] & G\times X\arrow[d,"\alpha"]\\
&X
\end{tikzcd}
%
\qquad
%
\begin{tikzcd}[column sep=large]
G\times G\times X\arrow[r,"{(m,1_X)}"]\arrow[d,swap,"{(1_G,\alpha )}"] & G\times
X\arrow[d,"\alpha"]\\
G\times X \arrow[r,"\alpha"]&X 
\end{tikzcd}
\]
\end{document}
