2020 年更新后使用 groupplot pgf tikz 获取每个图的子标题

我发现的所有解决方案都只适用于 2020 年之前，并且不再适用于最新的 caption.sty。

我将从 MWE 开始：

\documentclass[12pt]{article}
\usepackage{pgfplots}
    \usepgfplotslibrary{groupplots}
 
\usepackage{caption,subcaption}  
    \renewcommand\thesubfigure{(\alph{subfigure})}
 
\begin{document}
 
\begin{figure}[!h]
\centering
\begin{tikzpicture}
\begin{groupplot}[
group style={
group name=my plots,
group size= 3 by 3,
horizontal sep =1.5cm,
vertical sep =2cm},
width=2in
]
\nextgroupplot[]
\addplot[] {x^0};
 
\nextgroupplot[]
\addplot[] {x^1};
 
\nextgroupplot[]
\addplot[] {x^2};
 
\nextgroupplot[]
\addplot[] {x^3};
 
\nextgroupplot[]
\addplot[] {x^4};
 
\nextgroupplot[]
\addplot[] {x^5};
\end{groupplot}
 
% Bildunterschriften
\tikzset{SubCaption/.style={
text width=2in,yshift=-3mm, align=center,anchor=north
}}
 
\node[SubCaption] at (my plots c1r1.south) {\captionof{subfigure}{First graph\label{subplot:eins}}};
 
\node[SubCaption] at (my plots c2r1.south) {\captionof{subfigure}{Second graph\label{subplot:zwei}}};
 
\node[SubCaption] at (my plots c3r1.south) {\captionof{subfigure}{Third graph\label{subplot:drei}}};
 
 
\node[SubCaption] at (my plots c1r2.south) {\captionof{subfigure}{Fourth graph\label{subplot:vier}}};
 
\node[SubCaption] at (my plots c2r2.south) {\captionof{subfigure}{Fifth graph\label{subplot:fuenf}}};
 
\node[SubCaption] at (my plots c3r2.south) {\captionof{subfigure}{Sixth graph\label{subplot:sechs}}};
\end{tikzpicture}
\caption{All graphs}\label{fig:plots}
\end{figure}
 
\end{document}

正如您所见，四年前这种方法是这样的，所有单个图表都有以 a) 开头的子标题，但现在每个标题都是实际的图形标题……

我还收到以下所有标题行的错误消息： Package caption Error: Should not be used with subtype 'subfigure'.

有人知道目前可用于解决 pgf groupplot 中的标题问题的解决方案吗？

使用\subcaption而不是\captionof{subfigure}。\rewnewcommand\thesubfigure可以注释掉 。

\documentclass[12pt]{article}
\usepackage{pgfplots}
    \usepgfplotslibrary{groupplots}
 
\usepackage{caption,subcaption}  
%    \renewcommand\thesubfigure{(\alph{subfigure})}
 
\begin{document}
 
\begin{figure}[!h]
\centering
\begin{tikzpicture}
\begin{groupplot}[
group style={
group name=my plots,
group size= 3 by 3,
horizontal sep =1.5cm,
vertical sep =2cm},
width=2in
]
\nextgroupplot[]
\addplot[] {x^0};
 
\nextgroupplot[]
\addplot[] {x^1};
 
\nextgroupplot[]
\addplot[] {x^2};
 
\nextgroupplot[]
\addplot[] {x^3};
 
\nextgroupplot[]
\addplot[] {x^4};
 
\nextgroupplot[]
\addplot[] {x^5};
\end{groupplot}
 
% Bildunterschriften
\tikzset{SubCaption/.style={
text width=2in,yshift=-3mm, align=center,anchor=north
}}
 
\node[SubCaption] at (my plots c1r1.south) {\subcaption{First graph\label{subplot:eins}}};
 
\node[SubCaption] at (my plots c2r1.south) {\subcaption{Second graph\label{subplot:zwei}}};
 
\node[SubCaption] at (my plots c3r1.south) {\subcaption{Third graph\label{subplot:drei}}};
 
 
\node[SubCaption] at (my plots c1r2.south) {\subcaption{Fourth graph\label{subplot:vier}}};
 
\node[SubCaption] at (my plots c2r2.south) {\subcaption{Fifth graph\label{subplot:fuenf}}};
 
\node[SubCaption] at (my plots c3r2.south) {\subcaption{Sixth graph\label{subplot:sechs}}};
\end{tikzpicture}
\caption{All graphs}\label{fig:plots}
\end{figure}
 
\end{document}
