使用引脚边缘显示多轴图中不同线图对应的轴

我正在尝试使用 pin 选项从线图上定义的节点绘制一条 |- 路径，以指向与图对应的轴。我当前的代码和输出如下。

\documentclass{standalone}
\usepackage{pgfplots}
\pgfplotsset{compat=1.5}
\begin{document}
    \tikzstyle{every pin edge}=[->,solid]
    \begin{tikzpicture}[scale=1.5]
        \begin{axis}[
        xlabel=X1,
        ylabel = Y1,
        axis x line* = bottom,
        axis y line*=left,
        ymin=-1,
        ymax = 27,
        yticklabels={},
        xticklabels={}]
        \addplot[mark=diamond*,dashed,mark options={scale=3,solid}] coordinates {(0.6,18) (2.5,14.4) (13.5,8.2) (52.5,1.9)} node [pos=0.13,pin=-180:{}](A){};
        \end{axis}
        \begin{axis}[
        xlabel={\textcolor{red}{X2}},
        axis x line* = top,
        axis y line*=left,
        xticklabels={},
        yticklabels={},
        ymin=-1,ymax=27,
        ytick={}]
        \addplot[mark=diamond*,red,dashed,mark options={scale=3,solid}] coordinates {(0,24.7) (3,9.3) (10,3.4) (20,0.8)} node [pos=0.1,pin=-180:{}](A){};
        \end{axis}
        \begin{axis}[
        axis x line* = bottom,
        axis y line*=right,
        ymin=-1,ymax=20,
        xticklabels={},
        ylabel=Y2,
        yticklabels={}]
        \addplot[mark=triangle*,dashed,mark options={scale=3,solid}] coordinates {(0.6,0.1) (2.5,2.1) (13.5,2.6) (52.5,5.9)} node [pos=0.85,pin=0:{}](A){};
        \end{axis}
        \begin{axis}[
        axis x line* = top,
        axis y line*=right,
        x axis line style = red,
        x tick style={color=red},   
        ymin=-1,ymax=20,
        xticklabels={},
        ytick={},yticklabels={}]
        \addplot[mark=triangle*,red,dashed,mark options={scale=3,solid}] coordinates {(0,0.7) (3,1.9) (10,5.7) (20,17.1)} node [pos=0.85,pin=0:{}](A){};
        \end{axis}
    \end{tikzpicture}
\end{document}

在此处输入图片描述

是否可以绘制一条 |-> 路径，而不是从线图上定义的节点（在本例中为 `A'）绘制 -> 路径，以显示对应于不同图的 x 轴和 y 轴？

答案1

我假设您想要（左，上）轴组合指向左和上等等。最好不要为每个坐标分配相同的名称。

\documentclass{standalone}
\usepackage{pgfplots}
\pgfplotsset{compat=1.5}
\begin{document}
    %\tikzstyle{every pin edge}=[->,solid]
    \begin{tikzpicture}[scale=1.5]
        \begin{axis}[
        xlabel=X1,
        ylabel = Y1,
        axis x line* = bottom,%*suppresses the axis line arrows,
        axis y line*=left,
        ymin=-1,
        ymax = 27,
        yticklabels={},
        xticklabels={}]
        \addplot[mark=diamond*,dashed,mark options={scale=3,solid}] coordinates {(0.6,18) (2.5,14.4) (13.5,8.2) (52.5,1.9)} 
          coordinate [pos=0.13](A);
        \draw[->] (A) |- +(-10pt,-10pt);
        \end{axis}
        \begin{axis}[
        xlabel={\textcolor{red}{X2}},
        axis x line* = top,
        axis y line*=left,
        xticklabels={},
        yticklabels={},
        ymin=-1,ymax=27,
        ytick={}]
        \addplot[mark=diamond*,red,dashed,mark options={scale=3,solid}] coordinates {(0,24.7) (3,9.3) (10,3.4) (20,0.8)}
          coordinate [pos=0.1](A);
        \draw[->,red] (A) |- +(-10pt,10pt);
        \end{axis}
        \begin{axis}[
        axis x line* = bottom,
        axis y line*=right,
        ymin=-1,ymax=20,
        xticklabels={},
        ylabel=Y2,
        yticklabels={}]
        \addplot[mark=triangle*,dashed,mark options={scale=3,solid}] coordinates {(0.6,0.1) (2.5,2.1) (13.5,2.6) (52.5,5.9)}
          coordinate [pos=0.85](A){};
        \draw[->] (A) |- +(10pt,-10pt);
        \end{axis}
        \begin{axis}[
        axis x line* = top,
        axis y line*=right,
        x axis line style = red,
        x tick style={color=red},   
        ymin=-1,ymax=20,
        xticklabels={},
        ytick={},yticklabels={}]
        \addplot[mark=triangle*,red,dashed,mark options={scale=3,solid}] coordinates {(0,0.7) (3,1.9) (10,5.7) (20,17.1)}
          coordinate [pos=0.85](A){};
        \draw[->,red] (A) |- +(10pt,10pt);
        \end{axis}
    \end{tikzpicture}
\end{document}
