[Tex/LaTex] subfigures: caption for every row and every column

floatssubcaption

I have three models that I test under different parameter configurations. I created a figure where every column corresponds to a model. I would like to add the value of the parameter at the left of every row. After reading this answer, this is what I do:

\documentclass{article}

\usepackage[draft]{graphicx}
\usepackage{subcaption}

\begin{document}

\begin{figure}
\centering
\begin{subfigure}[t]{0.30\textwidth}
    \rotatebox[origin=c]{90}{$R=1$}
    \includegraphics[width=\textwidth]
    {test.png}
    \rotatebox[origin=c]{90}{$R=2$}
    \includegraphics[width=\textwidth]
    {test.png}
    \rotatebox[origin=c]{90}{$R=3$}
    \includegraphics[width=\textwidth]
    {test.png}
    \caption{model A}
\end{subfigure}
\hspace{1em}
\begin{subfigure}[t]{0.30\textwidth}
    \includegraphics[width=\textwidth]  
    {test.png}
    \includegraphics[width=\textwidth]
    {test.png}
    \includegraphics[width=\textwidth]
    {test.png}
    \caption{model B}
\end{subfigure}
\hspace{1em}
\begin{subfigure}[t]{0.30\textwidth}
    \includegraphics[width=\textwidth]  
    {test.png}
    \includegraphics[width=\textwidth]
    {test.png}
    \includegraphics[width=\textwidth]
    {test.png}
    \caption{model C}
\end{subfigure}
\caption{Grid test}
\end{figure}

But I get this:
test

How can I make it right?

One possibility (the % signs suppressing spurious blank spaces are essential):

Update

A modified version (the whole construct now stays inside the text width):

\documentclass{article}
\usepackage[draft]{graphicx}
\usepackage{subcaption}
\usepackage{showframe}% just for visiual guide

\begin{document}

\begin{figure}
\centering
\begin{subfigure}[t]{\dimexpr0.30\textwidth+20pt\relax}
    \makebox[20pt]{\raisebox{40pt}{\rotatebox[origin=c]{90}{$R=1$}}}%
    \includegraphics[width=\dimexpr\linewidth-20pt\relax]
    {test.png}
    \makebox[20pt]{\raisebox{40pt}{\rotatebox[origin=c]{90}{$R=2$}}}%
    \includegraphics[width=\dimexpr\linewidth-20pt\relax]
    {test.png}
    \makebox[20pt]{\raisebox{40pt}{\rotatebox[origin=c]{90}{$R=3$}}}%
    \includegraphics[width=\dimexpr\linewidth-20pt\relax]
    {test.png}
    \caption{model A}
\end{subfigure}\hfill
\begin{subfigure}[t]{0.30\textwidth}
    \includegraphics[width=\textwidth]  
    {test.png}
    \includegraphics[width=\textwidth]
    {test.png}
    \includegraphics[width=\textwidth]
    {test.png}
    \caption{model B}
\end{subfigure}\hfill
\begin{subfigure}[t]{0.30\textwidth}
    \includegraphics[width=\textwidth]  
    {test.png}
    \includegraphics[width=\textwidth]
    {test.png}
    \includegraphics[width=\textwidth]
    {test.png}
    \caption{model C}
\end{subfigure}
\caption{Grid test}
\end{figure}

\end{document}

The result:

(labels protrude to the left margin):

    \includegraphics[width=\textwidth]
    {test.png}
    \caption{model C}
\end{subfigure}
\caption{Grid test}
\end{figure}

Adjust the lengths in the \raiseboxes and the inner \makeboxes according to your needs.

[Tex/LaTex] custom sub-caption and refs format for subfigures

I don't think using three different formats for the numbering of subfigures is good. Anyway, here it is:

\documentclass{article}
\usepackage{caption}
\captionsetup[figure]{labelsep=period,justification=centering,singlelinecheck=off}
\DeclareCaptionLabelFormat{rightparen}{#2)}
\usepackage{subfig}
\captionsetup[subfloat]{labelformat=rightparen}
\showcaptionsetup[uniq]{subfloat}
\usepackage{xparse}

\ExplSyntaxOn
\seq_new:N \g_akj_subfloat_seq
\NewDocumentCommand{\xsubfloat}{ m m }
 {
  \akj_subfloat:nn { #1 } { #2 }
 }
\NewDocumentCommand{\makexcaption}{o}
 {
  \caption{\IfNoValueF{#1}{#1~}Subfigures:~%
  \seq_use:Nnnn \g_akj_subfloat_seq {;~} {;~} {;~}}
 }
\cs_new_protected:Npn \akj_subfloat:nn #1 #2
 {
  % initialize
  \int_compare:nT { \value{subfigure} = 0 }
   { \seq_gclear:N \g_akj_subfloat_seq }
  % do the subfloat
  \subfloat[]{#2}
  % store the subcaption
  \seq_gput_right:Nx \g_akj_subfloat_seq { (\exp_not:N\textit{\alph{subfigure}}) ~ \exp_not:n { #1 } }
 }
\ExplSyntaxOff
\renewcommand{\thesubfigure}{\textit{\alph{subfigure}}}
\makeatletter
\def\p@subfigure{\thefigure\,}
\makeatother

\begin{document}
\begin{figure}
\centering
\xsubfloat{subfigure A}{%
  \rule{100pt}{50pt}%
  \label{fig:subfig-a}%
}
\xsubfloat{subfigure B}{%
  \rule{100pt}{50pt}%
  \label{fig:subfig-b}%
}
\xsubfloat{subfigure C}{%
  \rule{100pt}{50pt}%
  \label{fig:subfig-c}%
}
\makexcaption\label{fig:figures}
\end{figure}

See Figures~\ref{fig:subfig-a}, \ref{fig:subfig-b} and~\ref{fig:subfig-c}.
\end{document}

The \makexcaption command has also an optional argument for text going before the list of subcaptions, so

\makexcaption[Some text.]

would produce

Figure 1. Some text. Subfigures: (a) subfigure A; (b) subfigure B; (c) subfigure C

Beware of unprotected end-of-lines in the arguments of \subfloat, that are the cause of your spurious spaces.

[Tex/LaTex] subfigure caption for all subfigures in a row (subfigure environment; subcaption package)

You can use the same subfigure environment for more than one figure:

\documentclass[a4paper,oneside,10pt]{scrartcl}
\usepackage{graphicx}
\usepackage{caption}
\usepackage{subcaption}

\begin{document}

\begin{figure}
    \centering
    \begin{subfigure}[b]{0.6\textwidth}
            \centering
            {\rule{3cm}{2cm}}\quad
            {\rule{3cm}{2cm}}
            \caption{Noon}
    \end{subfigure}\\
     \begin{subfigure}[b]{0.6\textwidth}
            \centering
            {\rule{3cm}{2cm}}\quad
            {\rule{3cm}{2cm}}
            \caption{Midnight}
    \end{subfigure}%
    \caption{Cool (left) and uncool (right) pictures; Recorded at noon (a) and at midnight (b).}
\end{figure}
