Disable references in pgfplot legends

Question

I would like to display a common legend for a groupplot like this:

\documentclass[crop]{standalone}
\usepackage[svgnames]{xcolor}
\usepackage{pgfplots}
\usepgfplotslibrary{groupplots}
\usepackage{hyperref}
\hypersetup{}
\begin{document}
\begin{tikzpicture}
  \begin{groupplot}[
    group style={
      {group size=1 by 1}},
    legend entries={A, B},
    legend columns=2,
    legend to name=grouplegend]
\nextgroupplot[title=One]
\addplot+[color=Blue] coordinates {(0,0) (1,1) (2,2)};
\addplot+[color=Red] coordinates {(0,2) (1,1) (2,0)};

\end{groupplot}
\node (l1) at ($(group c1r1.south)$)
  [below, yshift=-2\pgfkeysvalueof{/pgfplots/every axis title shift}]
  {\ref{grouplegend}};
\end{tikzpicture}
\end{document}

As seen in the result, the legend contains a reference to the figure (hyperref of course producing a box around it). Is there a way to disable this reference?

Answer 1

With this post Disable hyperref link for single footnote, I tried this:

\newcommand\blref[1]{%
  \begin{NoHyper}%
    \ref{#1}
  \end{NoHyper}%
}

The complet code

\documentclass[crop]{standalone}
\usepackage[svgnames]{xcolor}
\usepackage{pgfplots}
\pgfplotsset{compat=1.18}%<-- added
\usepgfplotslibrary{groupplots}
\usepackage{hyperref}
\hypersetup{}
\newcommand\blref[1]{%
  \begin{NoHyper}%
    \ref{#1}
  \end{NoHyper}%
}
\begin{document}
\begin{tikzpicture}
  \begin{groupplot}[
    group style={
      {group size=1 by 1}},
    legend entries={A, B},
    legend columns=2,
    legend to name=grouplegend]
\nextgroupplot[title=One]
\addplot+[color=Blue] coordinates {(0,0) (1,1) (2,2)};
\addplot+[color=Red] coordinates {(0,2) (1,1) (2,0)};

\end{groupplot}
\node (l1) at ($(group c1r1.south)$)
  [below, yshift=-2\pgfkeysvalueof{/pgfplots/every axis title shift}]
  {\blref{grouplegend}};
\end{tikzpicture}
\end{document}
