subfloats
I've a question on the labels in the subfigure environment. I would like to remove the (a) and (b) and insert something else instead. This 'new' caption is different for every subfigure and not a logical counter (so not i, ii or so).
Can any body help me?
I've added a figure showing the current situation (top) and how I would like it to be (bottom).
Here's a flexible solution; in a figure environment you define with \xsubfigure the objects you need and then arrange them as you like. Each command has as a first argument a symbolic key to be used in \makerow; the second argument defines the objects via a key-value syntax (add \label in the body of caption, if needed).
\documentclass{article}
\usepackage[font=footnotesize]{subcaption}
\usepackage[demo]{graphicx}
\usepackage{xparse}
\ExplSyntaxOn
\NewDocumentCommand{\xsubfigure}{ m m }
{% #1 is a symbolic key, #2 is a list of key-value pairs
\roly_xsubfigure:nn { #1 } { #2 }
}
\NewDocumentCommand{\makerow}{ m }
{% #1 is a list of symbolic keys
\roly_makerow:n { #1 }
}
% define the keys
\keys_define:nn { roly/subfigures }
{
width .tl_set:N = \l_roly_subfig_width_tl,
body .tl_set:N = \l_roly_subfig_body_tl,
caption .tl_set:N = \l_roly_subfig_caption_tl,
}
% the needed variables
\dim_new:N \l_roly_row_height_dim
\box_new:N \l_roly_body_box
% this is the inner command that stores the properties
\cs_new_protected:Npn \roly_xsubfigure:nn #1 #2
{
\prop_if_exist:cTF { l_roly_subfig_#1_prop }
{
\prop_clear:c { l_roly_subfig_#1_prop }
}
{
\prop_new:c { l_roly_subfig_#1_prop }
}
\keys_set:nn { roly/subfigures } { #2 }
\prop_put:cnV { l_roly_subfig_#1_prop } { width } \l_roly_subfig_width_tl
\prop_put:cnV { l_roly_subfig_#1_prop } { body } \l_roly_subfig_body_tl
\prop_put:cnV { l_roly_subfig_#1_prop } { caption } \l_roly_subfig_caption_tl
}
% this is the inner command for producing a row
\cs_new_protected:Npn \roly_makerow:n #1
{
% get the heights of the objects on a row
\dim_zero:N \l_roly_row_height_dim
\clist_map_inline:nn { #1 }
{
\hbox_set:Nn \l_roly_body_box
{
\prop_item:cn { l_roly_subfig_##1_prop } { body }
}
\dim_compare:nT { \box_ht:N \l_roly_body_box > \l_roly_row_height_dim }
{
\dim_set:Nn \l_roly_row_height_dim { \box_ht:N \l_roly_body_box }
}
}
% produce a line
\clist_map_inline:nn { #1 }
{
% a subfigure is set here
\begin{subfigure}[t]{ \prop_item:cn { l_roly_subfig_##1_prop } { width } }
\raggedright
\vspace{0pt} % for top alignment
% the body is set in a suitably dimensioned parbox
\parbox[t][\l_roly_row_height_dim]{\textwidth}{
\prop_item:cn { l_roly_subfig_##1_prop } { body }
}
% add the caption
\caption{ \prop_get:cn { l_roly_subfig_##1_prop } { caption } }
\end{subfigure}
\hspace{2em} % some space between the objects in a row
}
\unskip\\ % end up the row
}
\ExplSyntaxOff
\begin{document}
\begin{figure}
\captionsetup[subfigure]{justification=justified,singlelinecheck=false}
\centering
\xsubfigure{A}{
width=0.3\textwidth,
body={\includegraphics[width=3cm,height=2cm]{fig/workflow-S}},
caption={workflow $S$ and some text added to go to the next line}
}
\xsubfigure{B}{
width=0.5\textwidth,
body={\includegraphics[width=6cm,height=2.5cm]{fig/workflow-S-run}},
caption={run of $S$}
}
\xsubfigure{C}{
width=0.3\textwidth,
body={\includegraphics[width=2cm,height=1.5cm]{fig/workflow-S'}},
caption={workflow $S'$}
}
\xsubfigure{D}{
width=0.5\textwidth,
body={\includegraphics[width=4cm,height=1cm]{fig/workflow-S'-run}},
caption={run of $S'$}
}
\makerow{A,B}
\medskip
\makerow{C,D}
\caption{Here's a figure}
\end{figure}
\end{document}
Note that if you're not satisfied with the arrangement, you can rearrange the subfigures by saying, for instance,
\makerow{A,D}
\medskip
\makerow{C,B}
In the example I set height and width for every \includegraphics, as I don't have your images, but you can use the keys you prefer.
You can use
\addtocounter{subfigure}{-1}
as demonstrated in the following MWE:
% arara: pdflatex
\documentclass{article}
\usepackage{subfig}
\usepackage[demo]{graphicx}
\begin{document}
\begin{figure}
\centering
\subfloat[]{\includegraphics{image}} % label/numbering
\subfloat{\includegraphics{image}} % no label/numbering
\\
\addtocounter{subfigure}{-1}
\subfloat[]{\includegraphics{image}} % label/numbering
\subfloat{\includegraphics{image}} % no label/numbering
\\
\addtocounter{subfigure}{-1}
\subfloat[]{\includegraphics{image}} % label/numbering
\subfloat{\includegraphics{image}} % no label/numbering
\caption[Short caption.] {\label{fig:figure_label} Long caption.}
\end{figure}
\end{document}
Note that subfigure is obsolete, and you should use either subfig or subcaption instead; see What is the difference between \subfigure and \subfloat?, for example.
Best Answer
Just stack the subcaption text under the subfigure. You can change the fontsize of the subcaptions just by changing the
\footnotesizeto the desired size. The gap between figure and caption is controlled by the optional argument to\stackunderand is, in this example, set to5pt(the default is 3pt).Note that the subcaptions in this technique, will not automatically word-wrap. In your case, there was no need for wrapping, since they were short labels. If wrapping were needed, the last argument to
\stackundercould be a\parbox.I further assumed, that since you wished to remove the
(a),(b), that you had no desire to separately reference the individual subfigures. You can still reference the overall figure with\ref{}.
