# I am trying to break this standalone image into two rows

I have used standalone to generate this picture:

I would like to put C and D below A and B and aligned them. Is there a simple command line? Thank you very much for your time!

Here is my code:

\documentclass[12pt,a4paper,twoside]{standalone}
\usepackage{graphicx}
\usepackage{caption,subcaption}
\usepackage[utf8]{inputenc}
\usepackage{textcomp}
\usepackage{pgfplots}

\begin{document}
\begin{figure}[htbp]
\captionsetup[subfigure]{singlelinecheck=off,labelfont={bf}}
\renewcommand\thesubfigure{\Alph{subfigure}}
\begin{subfigure}{0.5\linewidth}
\centering
\includegraphics[width=\linewidth]{Figure2a}
\caption{}
\end{subfigure}%
\begin{subfigure}{0.5\linewidth}
\centering
\includegraphics[width=\linewidth]{Figure2b}
\caption{}
\end{subfigure}

\vspace{1cm}
\begin{subfigure}{0.5\linewidth}
\centering
\includegraphics[width=\linewidth]{Figure2c}
\caption{}
\end{subfigure}%
\begin{subfigure}{0.5\linewidth}
\centering
\includegraphics[width=\linewidth]{Figure2d}
\caption{}
\end{subfigure}

\end{figure}
\end{document}


Figure A:

Figure B

Figure C

Figure D

EDIT:

Here is my new code, which is a lot better than my previous one:

\documentclass[12pt,a4paper,twoside]{standalone}
\usepackage{graphicx}
\usepackage{caption,subcaption}
\usepackage[utf8]{inputenc}
\usepackage{textcomp}
\usepackage{pgfplots}
\graphicspath{{./Figures/}}
\begin{document}

\begin{table}[htbp]
\begin{tabular}{cc}
\includegraphics[width=\textwidth]{Figure3a.png} &
\includegraphics[width=\textwidth]{Figure3b.png} &\\
\includegraphics[width=\textwidth]{Figure3c.png} &
\includegraphics[width=\textwidth]{Figure3d.png}
\end{tabular}
\end{table}
\end{document}


I get the following:

I would greatly appreciate if someone could please show me how to add subcaptions (e.g. A, B, C, D) from left to right. Thank you!

• there is no need to figure environment. You can use tabular environment and may be caption package if you need captions. – touhami Apr 24 '15 at 18:55
• You would have to use two \includegraphics and crop half the image each time. – John Kormylo Apr 24 '15 at 19:04
• If you use a minipage inside standalone, you can arrange them vertically as well as horizontally. That won't help with the captions, though. – John Kormylo Apr 24 '15 at 19:06
• @touhami Thank you! It worked well! I have edited the code. However, I am still stuck at the caption. – Johnathan Apr 24 '15 at 19:54

I am not sure that this code will be useful to you?

\documentclass[12pt,a4paper,twoside]{standalone}
\usepackage{graphicx}
\usepackage[utf8]{inputenc}
\usepackage{textcomp}
\usepackage{pgfplots}
\begin{document}
\begin{tabular}{l l}
\includegraphics[width=\textwidth]{Figure3a.png} &
\includegraphics[width=\textwidth]{Figure3b.png} \\
{\Large\textbf{(A)}} & {\Large\textbf{(B)}} \\
\includegraphics[width=\textwidth]{Figure3c.png} &
\includegraphics[width=\textwidth]{Figure3d.png} \\
{\Large\textbf{(C)}} & {\Large\textbf{(D)}} \\
\end{tabular}
\end{document}


Use the varwidth option.

In the example I used .9\linewidth to emulate your images, because otherwise the example images would be squashed to one another horizontally. Also border=4 is for the same reason: the upper images would be too near the top. Such problems would not be present with your images, probably.

I'd recommend setting a margin for the subcaptions.

\documentclass[12pt,a4paper,varwidth,border=4]{standalone}
\usepackage{graphicx}
\usepackage{caption,subcaption}

\captionsetup[subfigure]{singlelinecheck=off,labelfont={bf}}
\renewcommand\thesubfigure{\Alph{subfigure}}

\begin{document}
\begin{figure}
\begin{subfigure}{0.5\linewidth}
\centering
\includegraphics[width=.9\linewidth]{example-image-a}
\caption{}
\end{subfigure}%
\begin{subfigure}{0.5\linewidth}
\centering
\includegraphics[width=.9\linewidth]{example-image-b}
\caption{}
\end{subfigure}

\vspace{1cm}
\begin{subfigure}{0.5\linewidth}
\centering
\includegraphics[width=.9\linewidth]{example-image-c}
\caption{}
\end{subfigure}%
\begin{subfigure}{0.5\linewidth}
\centering
\includegraphics[width=.9\linewidth]{example-image}
\caption{}
\end{subfigure}

\end{figure}
\end{document}
