Graphics, Figures & Tables ⇒ subcaption | Labels of Sub-floats on left Side

[dcernst]

I'm looking for a way to put the labels for subfloats in a figure environment on the left while the label and caption for the figure stay on the bottom. I want to do this for a few figures and not globally for all of them. Also, in these cases, the caption for the floats is empty. Here is my setup in a minimal example:

Code: Select all

\documentclass[11pt]{amsart}

\usepackage{graphicx}
\usepackage{caption}
\usepackage[labelformat=simple,labelfont={}]{subcaption}

\begin{document}
yada yada, check out my cool figure.

\begin{figure}[!ht]
\centering
\subfloat[\label{Fig135}]{\includegraphics[scale=.95]{Fig135}}
\subfloat[\label{Fig136}]{\includegraphics[scale=.95]{Fig136}}
\caption{Cool figures}\label{Fig135--Fig136}
\end{figure}

That's all for now...

\end{document}

I'm hoping to get the labels (a) and (b) to appear on the left and centered vertically. It may be worth noting that in each of the cases that I want to do this, the images in the subfloats are too wide to sit side by side. Thanksl

I suggest to take a look at Section 6 of the floatrow manual. It discusses possible setups in conjunction with the caption package. Perhaps you can find something useful for you. In case of upcoming problems, feel free to ask further questions.

I'm attempting to sort things out with the floatrow package, but not having much luck. I can't get even a simple example to compile. All the examples in the documentation are filled with ... and it isn't clear to me where to put the various components. In particular, where does \includegraphics{} go? Also, it isn't clear to me how to implement the types of changes that I want to make locally as opposed to globally. Any further input would be greatly appreciated.

If you don't want to use the floatrow package, you can build the requested layout by hand, i.e. using \parbox'es or minipages. For example:

Code: Select all

\documentclass[11pt]{amsart}

\usepackage[demo]{graphicx}
\usepackage{caption}
\usepackage[labelformat=simple,labelfont={}]{subcaption}

\begin{document}
yada yada, check out my cool figure.

\begin{figure}[!ht]
\centering
\begin{subfigure}[b]{0.45\textwidth}
\caption{}\label{Fig135}
\end{subfigure}
\begin{minipage}[b]{0.45\textwidth}
\includegraphics[scale=.95]{Fig135}
\end{minipage}
\\[1ex]
\begin{subfigure}[b]{0.45\textwidth}
\caption{}\label{Fig136}
\end{subfigure}
\begin{minipage}[b]{0.45\textwidth}
\includegraphics[scale=.95]{Fig136}
\end{minipage}
\caption{Cool figures}\label{Fig135--Fig136}
\end{figure}

That's all for now...

\end{document}

(Please note that I have added the "demo" option to the graphicx package since I don't have your picture files.)

I notice that you replaced \subfloat with \subfigure and in another recent post of yours, you said to use \subcaptionbox instead of \subfloat. What's the difference between \subfigure and \subcaptionbox here? Thanks! (I'll close the topic once I've verified that this works for me.)

OK, I'm getting closer, but I'm not there yet. Even with messing around with the width of the minipage and subfigure, I can't get things to look right. Here is my most recent attempt using \subcaptionbox:

Code: Select all

\documentclass[11pt]{amsart}

\usepackage[demo]{graphicx}
\usepackage{caption}
\usepackage[labelformat=simple,labelfont={}]{subcaption}

\begin{document}
yada yada, check out my cool figure.

\begin{figure}[!ht]
\centering
\subcaptionbox{\label{Fig135}}{}
\begin{minipage}[c]{.6\textwidth}
\includegraphics[scale=.95]{Fig135}
\end{minipage}
\\[1ex]
\subcaptionbox{\label{Fig136}}{}
\begin{minipage}[c]{0.6\textwidth}
\includegraphics[scale=.95]{Fig136}
\end{minipage}
\caption{Cool figures}\label{Fig135--Fig136}
\end{figure}

That's all for now...

\end{document}

However, in this case, the subfigure labels overlap the left end of the image. Also, the label isn't quite centered vertically.

The subcaption package offers \subcaption, \subcaptionbox, and the subfigure resp. subtable environment. For an explanation of them please take a look at the subcaption package documentation.

OK, I'm getting closer, but I'm not there yet.

What is not working or wrong with the version I have posted?

\subcaptionbox{\label{Fig135}}{}

This does not work because a \subcaptionbox will have the width of its contents (at least by default). So the above box will have a width of 0pt.

So if you want to typeset a sub-caption without context, better use \subcaption or the subfigure environment instead.

I've attached the output for your code using my figures. As you can see, the horizontal spacing is off and despite playing around with various values, I couldn't get it to look right. Also, I'm hoping to have the label centered vertically.

As you can see, the horizontal spacing is off

This is controlled by the widths of the minipages. Since I don't have your graphic files I was not able to give them proper values. (I have changed them a bit now.)

Also, I'm hoping to have the label centered vertically.

This can be done by changing the minipage alignment option from "b" to "c", e.g.:

Code: Select all

\documentclass[11pt]{amsart}

\usepackage[demo]{graphicx}
\usepackage{caption}
\usepackage[labelformat=simple,labelfont={}]{subcaption}

\begin{document}
yada yada, check out my cool figure.

\begin{figure}[!ht]
\centering
\begin{subfigure}[c]{0.1\textwidth}
\caption{}\label{Fig135}
\end{subfigure}%
\begin{minipage}[c]{0.9\textwidth}
\includegraphics[width=\linewidth]{Fig135}
\end{minipage}
\\[1ex]
\begin{subfigure}[c]{0.1\textwidth}
\caption{}\label{Fig136}
\end{subfigure}%
\begin{minipage}[c]{0.9\textwidth}
\includegraphics[width=\linewidth]{Fig136}
\end{minipage}
\caption{Cool figures}\label{Fig135--Fig136}
\end{figure}

That's all for now...

\end{document}

Yes, this looks much better. Is there a way to determine the exact width of an eps file? That way I could figure out how wide to make the minipages. Then I think I can nail this down. Thanks (again) for all the help.
