Drawing a line from one axis to another

[leon-9]

Hi there,

In the following example,

\documentclass{minimal}
\usepackage{pgfplots}
\begin{document}
\begin{tikzpicture}
  \begin{axis}[name=axis1]
    \addplot coordinates {
      (0.1,0.2)
      (1.1,1.2)
    };
  \end{axis}
  \begin{axis}[at={(axis1.east)},anchor=west,xshift=1cm]
    \addplot coordinates {
      (0.1,0.2)
      (1.1,1.2)
    };
  \end{axis}
\end{tikzpicture}
\end{document}

How to draw a line between a point on the first axis to the second one?
Thank you very much.

Best wishes,
Leo

I tried placing a named coordinate inside one axis and using it in
another. It failed.

Miraculously I can use the coordinate outside axis env. So I have
reached the following solution:

\documentclass{minimal}
\usepackage{pgfplots}
\begin{document}
\begin{tikzpicture}
  \begin{axis}[name=axis1]
    \addplot coordinates {
      (0.1,0.2)
      (1.1,1.2)
    };
    \coordinate (A) at (rel axis cs:0.2,0.2);
  \end{axis}
  \begin{axis}[at={(axis1.east)},anchor=west,xshift=1cm]
    \addplot coordinates {
      (0.1,0.2)
      (1.1,1.2)
    };
    \coordinate (B) at (rel axis cs:0.2,0.2);
  \end{axis}
  \draw (A) -- (B);
\end{tikzpicture}
\end{document}

Hello Leo,

This is the only solution I can think of. The same has been done in this
example :
