# subfloat - issues with the subcaption

I am new at LaTeX and I have been some problems with the subcaption text, since I have to put five images in a singe row. I have the follow code for this:

\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage{subfig}
\usepackage{graphicx}

\begin{document}

\begin{figure}[h!]
\centering
\subfloat[Standart Reification]{\includegraphics[width=0.2\textwidth]{example-image-a}}
\subfloat[Named Graphs]{\includegraphics[width=0.2\textwidth]{example-image-b}}
\subfloat[n-ary  Relations]{\includegraphics[width=0.2\textwidth]{example-image-c}}
\subfloat[Singleton Properties]{\includegraphics[width=0.2\textwidth]{example-image-a}}
\subfloat[NdFluents]{\includegraphics[width=0.2\textwidth]{example-image-b}}
\caption{RDF Approaches}
\label{fig:subfigures}
\end{figure}

\end{document}


And my output image, have been looking like this:

The first four subcaptions has a weird alignment. How can I resolve this alignment problem, making the subcaptions looking like the last subcaption?

• Welcome to TeX.SX! Please make your code compilable (if possible), or at least complete it with \documentclass{...}, the required \usepackage's, \begin{document}, and \end{document}. That may seem tedious to you, but think of the extra work it represents for TeX.SX users willing to give you a hand. Help them help you: remove that one hurdle between you and a solution to your problem. – Stefan Pinnow Jul 23 '18 at 14:16
• Oh, really sorry, from now my code is compiling. Thanks for the advice :) – Romão Martines Jul 23 '18 at 14:28
• The first four sub-captions are simply too long to fit in 1/5 of \textwidth. P.S. Your code is still not compilable to us because we don’t have your image files .png. – Ruixi Zhang Jul 23 '18 at 14:31

You can achieve the alignment of the sub-captions by explicitly setting the alignment for the sub-captions.

\captionsetup[subfigure]{format=hang,justification=raggedright}

If you really want the captions all in one line, you would have to change the fontsize.

With the more recent subcaption package and it's provided subfigure this would look like:

## Code

\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage{subcaption}
\usepackage{graphicx}

\captionsetup[subfigure]{format=hang,justification=raggedright}
\begin{document}
\begin{figure}[h!]
\centering
\begin{subfigure}[t]{0.2\textwidth}
\includegraphics[width=\textwidth]{example-image-a}
\caption{Standart Reification}
\label{fig:ExampleA}
\end{subfigure}%
\begin{subfigure}[t]{0.2\textwidth}
\includegraphics[width=\textwidth]{example-image-b}
\caption{Named Graphs}
\label{fig:ExampleB}
\end{subfigure}%
\begin{subfigure}[t]{0.2\textwidth}
\includegraphics[width=\textwidth]{example-image-c}
\caption{n-ary  Relations}
\label{fig:ExampleC}
\end{subfigure}%
\begin{subfigure}[t]{0.2\textwidth}
\includegraphics[width=\textwidth]{example-image-c}
\caption{Singleton Properties}
\label{fig:ExampleD}
\end{subfigure}%
\begin{subfigure}[t]{0.2\textwidth}
\includegraphics[width=\textwidth]{example-image-b}
\caption{NDFlunents}
\label{fig:ExampleE}
\end{subfigure}
\caption{RDF Approaches}
\end{figure}
