![禁用 pgfplot 图例中的引用](https://linux22.com/image/461127/%E7%A6%81%E7%94%A8%20pgfplot%20%E5%9B%BE%E4%BE%8B%E4%B8%AD%E7%9A%84%E5%BC%95%E7%94%A8.png)
我想显示一个groupplot
像这样的常见图例:
\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}
从结果中可以看出,图例包含对图形的引用(hyperref 当然会在其周围产生一个框)。有没有办法禁用此引用?
答案1
通过这篇文章禁用单个脚注的超链接,我尝试了这个:
\newcommand\blref[1]{%
\begin{NoHyper}%
\ref{#1}
\end{NoHyper}%
}
完整代码
\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}
