Graphics, Figures & Tables ⇒ Figure labeling

[Amitavo Roy]

I would like to add two figures (one below the another-named them a and b respectively),
I used

Code: Select all

\begin{figure}[!h]
  \centering
  \includegraphics[width=0.8\linewidth]{52a}
  \includegraphics[width=0.8\linewidth]{52b}
    \caption{(a) Study of convergence..., (b) zoomed picture of the encircled   
             portion of (a).....}
    \label{fig:5.2a}
    \label{fig:5.2b}
\end{figure}

After runing this code line I can ref. only fig. 5.2 in my text...but I want to ref. in some places with fig. 5.2a and in some places with fig. 5.2b.

My question is thus: how can I label my figures with two different labels?
Thanks for your help

One option would be using the/my subcaption package. It offers a command called \phantomcaption which does all a regular \caption does (incrementing the figure or sub-figure counter, generating an anchor for \label and \ref, ...) but does not actually typeset a caption text.

For example:

Code: Select all

\documentclass{article}
\usepackage[demo]{graphicx}
\usepackage{subcaption}
\begin{document}
\verb|\ref{fig:5.2a}| gives \ref{fig:5.2a} and
\verb|\ref{fig:5.2b}| gives \ref{fig:5.2b}.
\begin{figure}
  \centering
  \begin{subfigure}{0.8\linewidth}
    \includegraphics[width=\hsize]{52a}
    \phantomcaption
    \label{fig:5.2a}
  \end{subfigure}
  \begin{subfigure}{0.8\linewidth}
    \includegraphics[width=\hsize]{52b}
    \phantomcaption
    \label{fig:5.2b}
  \end{subfigure}
  \caption{(a) Study of convergence..., (b) zoomed picture of the encircled   
             portion of (a).....}
\end{figure}
\end{document}
