Graphics, Figures & Tables ⇒ Subfigure and legend

[elglanto]

Hello there,

In a document i'm writting, i need sometime to put several images in the same figure. For this, i use subfigure. Here is an exemple of what i wrote for two images:

Code: Select all

\begin{figure}[htbp]
        \begin{subfigure}[b]{0.5\textwidth}
                \centering
                \includegraphics[width=\textwidth]{image1.pdf}
                \caption{Legend1}
                \label{fig:image1}
        \end{subfigure}%
        ~
        \begin{subfigure}[b]{0.5\textwidth}
                \centering
                \includegraphics[width=\textwidth]{image2.pdf}
                \caption{Legend}
                \label{fig:image2}
        \end{subfigure}
        \caption{General legend}
        \label{fig:images}
\end{figure}

It usually works quite well but i'm having some trouble when the text of Legend1 or Legend2 use more lines than the other one. Then, the two subfigures are no more aligned. Is there a way to solve this problem?

Thanks for your help and please excuse my english, i'm not a native speaker.

My packages are the folowing:

Code: Select all

\usepackage[utf8]{inputenc}
\usepackage[english,francais]{babel}
\usepackage{xspace}
\usepackage{amsmath,amsthm}
\usepackage{amsfonts}
\usepackage{graphicx}% Include figure files
\usepackage{dcolumn}% Align table columns on decimal point
\usepackage{bm}% bold math
\usepackage{caption}
\usepackage{subcaption}
\usepackage[final]{pdfpages}

What alignment do you want to have? If you want to have an alignment to the top of the subfigures, don't use but [t] instead. If you want to have an alignment to the very first caption/legend line, don't use the subfigure environment at all but the \subcaptionbox command instead.

Thanks, the work perfectly. But just for my knowledge, how should i use \subcaptionbox?

Just as stated in the subcaption package documentation, e.g.:

Code: Select all

\subcaptionbox{Legend1\label{fig:image1}}
  {\includegraphics[width=0.5\textwidth]{image1.pdf}}
