有没有办法在 TiKz/pgfplot 中的子图之间绘制某种联系，就像这样例子? 我希望实现这样的目标：
但我需要在图表之间画一条“x 2000”的线。
编辑：所以现在我有这样的东西：
来自我的main.tex：

\usepackage[usenames,dvipsnames]{xcolor}
\usepackage{cleveref}

\pgfplotsset{

}

答案1
请考虑提供可编译的示例，正如您在下面看到的，它不超过 10 行，但使问题更容易回答。
您可以使用轴坐标保留坐标以供日后使用。
\documentclass{article}
\usepackage{pgfplots}
\pgfplotsset{compat=1.8}
\begin{document}
\begin{tikzpicture}
\begin{axis}[width=3cm,height=5cm,after end axis/.append code={\coordinate (a) at (axis description cs:1,0);}]
\end{axis}
\begin{scope}[xshift=4cm]
\begin{axis}[after end axis/.append code={\coordinate (b) at (axis description cs:0,1);}]
\end{axis}
\draw[gray] (a) -- (b) node[pos=0.5,sloped,fill=white] {$x=2000$};
\end{scope}
\end{tikzpicture}
\end{document}
答案2
我发现这比接受的答案稍微清楚一点：
\documentclass{article}
\usepackage{pgfplots}
\usetikzlibrary{calc}
\pgfplotsset{compat=1.8}
\begin{document}
\begin{tikzpicture}
\begin{axis}[width=3cm,height=5cm,name=a]
\end{axis}
\begin{axis}[width=10cm,height=10cm,name=b,at={($(a.south east)+(5cm,0)$)}]
\end{axis}
\draw[gray] (a.south east) -- (b.north west) node[pos=0.5,sloped,fill=white] {$x=2000$};
\end{tikzpicture}
\end{document}
