Figure not automatically being placed on two pages

Question

My figures are not being placed on 2 pages, instead they are disappearing off the end of the first page.

\documentclass{amsart}
\usepackage{graphicx}
\usepackage{subfig}
\begin{document}
  \begin{figure}[!ht]
  \centering\makebox[\textwidth]{
  \begin{tabular}{c}
  \subfloat[Infectious patient=1]{\label{fig:Yw_YAB_HBN4_pos_1_all.pdf}\includegraphics[width=12cm,height=6cm]{./Figures/chapter7/Yw_YAB_HBN4_pos_1_all.pdf}}\
  \subfloat[Infectious patient=2]{\label{fig:Yw_YAB_HBN4_pos_2_all.pdf}\includegraphics[width=12cm,height=6cm]{./Figures/chapter7/Yw_YAB_HBN4_pos_2_all.pdf}}\
  \subfloat[Infectious patient=3]{\label{fig:Yw_YAB_HBN4_pos_1_all.pdf}\includegraphics[width=12cm,height=6cm]{./Figures/chapter7/Yw_YAB_HBN4_pos_3_all.pdf}}\
  \subfloat[Infectious patient=4]{\label{fig:Yw_YAB_HBN4_pos_1_all.pdf}\includegraphics[width=12cm,height=6cm]{./Figures/chapter7/Yw_YAB_HBN4_pos_4_all.pdf}}
     \end{tabular}
}%}
 \smallskip
  \caption{Comparison of CFU values (Y) normalised against YAB single room \emph{direct care} after hand hygiene between YAB single room and HBN04-01 4-bed room}
  \label{fig:Yw_YAB_HBN4}
\end{figure}
\end{document}

Page breaks in table rows addresses the problem in tables. Is this what I need too?

Answer 1

So here is the code:

\documentclass{amsart}

\usepackage{graphicx}
\usepackage{subfig}

\begin{document}
\begin{figure}[!ht]
  \centering
  \subfloat[Infectious patient=1]{\label{fig:Yw_YAB_HBN4_pos_1_all.pdf}\includegraphics[width=12cm,height=6cm]{./Figures/chapter7/Yw_YAB_HBN4_pos_1_all.pdf}}\\
  \subfloat[Infectious patient=2]{\label{fig:Yw_YAB_HBN4_pos_2_all.pdf}\includegraphics[width=12cm,height=6cm]{./Figures/chapter7/Yw_YAB_HBN4_pos_2_all.pdf}}
  \caption{Comparison of CFU values (Y) normalised against YAB single room \emph{direct care} after hand hygiene between YAB single room and HBN04-01 4-bed room (continued on next page)}
\end{figure}  

\begin{figure}[!ht]
  \ContinuedFloat
  \centering
  \subfloat[Infectious patient=3]{\label{fig:Yw_YAB_HBN4_pos_3_all.pdf}\includegraphics[width=12cm,height=6cm]{./Figures/chapter7/Yw_YAB_HBN4_pos_3_all.pdf}}\\
  \subfloat[Infectious patient=4]{\label{fig:Yw_YAB_HBN4_pos_4_all.pdf}\includegraphics[width=12cm,height=6cm]{./Figures/chapter7/Yw_YAB_HBN4_pos_4_all.pdf}}
%}
  \smallskip
  \caption[]{Comparison of CFU values (Y) normalised against YAB single room \emph{direct care} after hand hygiene between YAB single room and HBN04-01 4-bed room (continued from previous page)}
  \label{fig:Yw_YAB_HBN4}
\end{figure}

\end{document}

Which will result in something like this:

The magic is done by the \continueFloat command, which prevents the figure (float) numbering from advancing, but increments the subfloat counter. It needs to be placed at the beginning of the next part of the float.

Notice the empty optional argument in the second figure (float) caption. It is necessary to avoid subsequent float entries from appearing as duplicates on the List-of-Floats page (if you have one).

If you want to avoid the caption after the first group of floats (i.e. have only a caption after all the floats have been typeset), you can define a caption style (the caption package that enables this feature is loaded anyway with subfig), which makes the label invisible in the preamble:

\DeclareCaptionLabelFormat{nocaption}{}

and where you don't want a caption to appear:

\captionsetup{labelformat=nocaption}
\caption[]{}
