How can i change the legend position in a multi-columns paper? Is there anything wrong with my code? I would like to put the legend in the top center of those two figures.

Thanks.

\begin{figure}[t]
\ref{testLegend}
\subfigure[Figure 1]{
\begin{tikzpicture}
\begin{axis}[xlabel={x}, ylabel={y}, width=4cm, ylabel near ticks, xlabel near ticks, y label style={font=\small}, x label style={font=\small}, ymajorgrids, cycle list name=exotic]
\addplot coordinates {(0,0) (1,1)};
\addplot coordinates {(0,0) (1,2)};
\end{axis}
\end{tikzpicture}
\label{fig:a}
}
\vspace{-1em}
\subfigure[Figure 2]{
\begin{tikzpicture}
\begin{axis}
[xlabel={x}, ylabel={y}, width=4cm, ylabel near ticks, xlabel near ticks, y label style={font=\small}, x label style={font=\small}, legend entries={line1, line2}, legend columns=2, legend to name=testLegend, legend style={font=\scriptsize}, legend pos=north east, legend style={font=\small}, ymajorgrids, cycle list name=exotic]
\addplot coordinates {(0,0) (1,1)};
\addplot coordinates {(0,0) (1,2)};
\end{axis}
\end{tikzpicture}
\label{fig:b}
} 
\caption{Caption test, \label{fig:c}}
\vspace{-1.5em}
\end{figure}

However, i want this result,

  • unrelated but never use \center the command form is \centering – David Carlisle Jan 22 '21 at 17:39
  • From your use of \subfigure I guess, you currently use the subfigure package. Please be aware that this package si considered obsolete. Instead, you can either use the subfig or the subcaption package. – leandriis Jan 22 '21 at 18:53
  • Since you seem to be unsatisfied with the current position of the legend: what exactly does "top center of those two figures" refer to? Probably a sketch of the expected output would help here? Please also make your code compilable by adding the documentclass as well as the relevant package. (See also: minimal working example (MWE)) – leandriis Jan 22 '21 at 18:55

With a custom edfined axis style to avoid repetition, subfig instead of the deprecated subfigure package and a separate tikzpicture for the legend:

enter image description here

\documentclass[twocolumn]{article}
\usepackage{pgfplots}
\usepackage{subfig}

\pgfplotsset{
    compat=1.17,
    my axis style/.style={
        xlabel={x}, 
        ylabel={y}, 
        width=4cm, 
        ylabel near ticks, 
        xlabel near ticks, 
        y label style={font=\small}, 
        x label style={font=\small}, 
        ymajorgrids, 
        cycle list name=exotic
        },
    }

    \node[draw=black, inner sep=6pt]{\ref{plot:teal} line1   \ref{plot:orange} line2};
  \end{tikzpicture}


\subfloat[Figure 1]{
    \begin{tikzpicture}
      \begin{axis}[my axis style]
      \addplot coordinates {(0,0) (1,1)}; \label{plot:teal}
      \addplot coordinates {(0,0) (1,2)}; \label{plot:orange}
      \end{axis}
    \end{tikzpicture}
    \label{fig:a}
  }
  \hfill
  \subfloat[Figure 2]{
    \begin{tikzpicture}
      \begin{axis}[my axis style]
      \addplot coordinates {(0,0) (1,1)};
      \addplot coordinates {(0,0) (1,2)};
      \end{axis}
