从插图到主图的箭头

我想从插图中绘制一个指向主图的箭头。问题是这两个图中的坐标位置不同。我想要的是： 在此处输入图片描述

我得到的是：

任何帮助都将不胜感激。谢谢。

这是我的 MWE：

\documentclass[12pt]{article}

\usepackage{pgfplots}
\usepackage{tikz}

\begin{document}
\begin{figure}[h!]
  \begin{center}

  \begin{tikzpicture}
  \begin{axis}[%

  \node (pairs_d) at (rel axis cs:0.9,0.1) {};
  \draw[->,>=stealth](pairs_s) -- (pairs_d);
  \end{axis}
  \end{tikzpicture}%

  \end{center}
\end{figure}
\end{document}

答案1

在局部坐标系中定义坐标，并在周围的tikzpicture中绘制箭头。

\begin{tikzpicture}
\begin{axis}
...
\coordinate (arrowFrom) at (axis cs:....);
\end{axis}
\begin{axis}
...
\coordinate (arrowTo) at (axis cs:....);
\end{axis}
\draw[->] (arrowFrom) -- (arrowTo);
\end{tikzpicture}

\begin{document}
  \begin{tikzpicture}
  \begin{axis}[%

  \coordinate (insetPosition) at (axis cs:0.65,300);
  \coordinate (arrowTo) at (axis cs:0.7,120);

  \addplot [color=black,solid,line width=0.5pt]
    table[row sep=crcr]{%
  1 20\\
  10 0\\
  };
  \coordinate (arrowFrom) at (axis cs:8,15);

  \draw[-stealth,red](arrowFrom) node[above]{\tiny Pairs} -- (arrowTo);

答案2

  • 将pairs_d node定义从第二个环境移到第一个axis环境；（正如@gernot所建议的，更改\node (name) at (where) {};为\coordinate (name) at (where);以获得更清洁的来源。）
  • 将选项添加remember picture到tikzpicture环境中；
  • 添加一个tikzpicture环境，remember picture, overlay其中包含draw从一个点到另一个点的线的选项。

当@gernot 发布他的答案时，我已经在写这个答案了，说实话，他的答案比我的干净得多。
