# captions not appearing below subfigure

Code:

\documentclass[fleqn,11pt,a4paper]{article}
\usepackage{geometry,array,graphicx,float,caption}
\usepackage{subcaption}

\begin{document}
\begin{figure}[H]
\centering
\begin{subfigure}{0.5\textwidth}
\includegraphics[width=6cm]{initial_normal.eps}
\caption{Normal Distribution}
\label{fig1a}
\end{subfigure}%
\begin{subfigure}{0.5\textwidth}[H]
\includegraphics[width=6cm]{initial_uniform.eps}
\caption{Uniform Distribution}
\label{fig1b}
\end{subfigure}
\caption{distributions}
\end{figure}
\end{document}


The captions should come below the figure but I am getting them to the right of the figures and the caption text is aligned centrally with respect to the page instead of the subfigure. Am I making a mistake here?

You should not put [H] after \begin{subfigure}{\textwidth}[H] Further, these points may be noted:

1. Don't put a blank line in between the subfigures.
2. The sum of widths of two subfigure should not exceed \textwidth
3. Put a % after the first subfigure if you specify a width of 0.5\textwidth for both subfigures. If the sum is less than \textwidth, you may put a \hfill in between.

\documentclass[fleqn,11pt,a4paper,demo]{article}
\usepackage{geometry,array,graphicx,float,caption}
\usepackage{subcaption}

\begin{document}
\begin{figure}[H]
%    \centering
\begin{subfigure}{0.5\textwidth}
\centering
\includegraphics[width=6cm]{initial_normal.eps}
\caption{Normal Distribution}
\label{fig1a}
\end{subfigure}%   %% This % is needed when you use 0.5\textwidth
%  Don't leave the blank line
\begin{subfigure}{0.5\textwidth}%[H]   %% Don't put this here
\centering
\includegraphics[width=6cm]{initial_uniform.eps}
\caption{Uniform Distribution}
\label{fig1b}
\end{subfigure}
\end{figure}
\end{document}


May be the subcaption package manual is useful here. You can access it by typing texdoc subcaption from command line/prompt. The correct usage for subfigure is

\begin{subfigure}[<pos>]{<width>}

... content like \includegraphics and caption

\end{subfigure}


Here <pos> is t or b c (default). Both [<pos>]{<width>} are same as that for a minipage.

• See even in your case the the subfigure caption is not directly below the subfigure.. Mine is worse still; I am not getting the neat composite figure as shown in all the examples. No difference in my code!! – WYSIWYG Aug 12 '14 at 9:03
• @bharat_iyengar Where do you want the caption? Both figure and caption centered or left aligned? – user11232 Aug 12 '14 at 9:05
• Figures side by side and their captions centrally aligned with respect to the subfigure (not the page). Just like this – WYSIWYG Aug 12 '14 at 9:07
• thanks harish.. i made an edit.. the captions are still not quite in their position. And what is the logic of putting a % after \end{subfigure} – WYSIWYG Aug 12 '14 at 9:25
