# Vertical placement of subfigs adjacent to another subfig

I have been using LyX, so I am fairly new to manipulating the underlying LaTeX. I have some images that I would like to arrange in a complicated fashion. The format I would like looks like

| Fig_A1 |  F   |
|        |  i   |
| Fig_A2 |  g_B |
|        |      |
|   F i g _ C   |


where each Fig_X is a subfloat. I used a tabular layout to force the positioning of the images. However, the output generates two pages: the first is blank, and the second has the figures Fig_A1/2 shifted toward the bottom of the page pushing Fig_C off. Fig_B is fine, though. It looks like this

|        |  F   |
|        |  i   |
|        |  g_B |
| Fig_A1 |      |
| Fig_A2 |      |


Here is the relevant section from my tex file exported from LyX.

%Preamble
\usepackage{float}
\usepackage{graphicx}
\@ifundefined{showcaptionsetup}{}{%
\PassOptionsToPackage{caption=false}{subfig}}
\usepackage{subfig}
\usepackage{babel}
% End Preamble

\begin{figure}[H]

\begin{tabular*}{0.9\paperwidth}{@{\extracolsep{\fill}}cc}
\subfloat[Figure A]{%
\begin{tabular}{c}
\includegraphics[width=2in,height=2in]{Fig_A1}\\
\includegraphics[width=2in,height=2in]{Fig_A2}\\
\end{tabular}
} &
\subfloat[Figure B]{%
\includegraphics[width=3in,height=4in]{Fig_B}
}%
\\
\multicolumn{2}{c}{\subfloat[Figure C]{Fig_C}}}\\
\end{tabular*}

\end{figure}


Does anyone see a reason why the tabular formatting is not being enforced?

I got the idea for using this type of formatting from how to put subfigures in several rows

Usually when LaTeX posts a blank page before inserting "something", it means that the "something" is too large to fit on a page. Please try to scale all the graphics to one half and see if the error still occurs. –  tohecz Jul 9 '12 at 5:59

I get a correct result with something like

\begin{figure}[p]

\begin{tabular}{cc}
\subfloat[Figure A]{%
\begin{tabular}[b]{@{}c@{}}
\includegraphics[width=2in,height=2in]{Fig_A1}\\
\includegraphics[width=2in,height=2in]{Fig_A2}\\
\end{tabular}
} &
\subfloat[Figure B]{%
\includegraphics[width=3in,height=4in]{Fig_B}
}%
\\
\multicolumn{2}{c}{\subfloat[Figure C]{\includegraphics[width=5in,height=2in]{Fig_C}}}\\
\end{tabular}

\end{figure}


Note the [b] argument to the inner tabular. I've added some dimensions to the last figure, which seemed missing. Note that such a big float should not receive the [H] specifier, but rather a [p] specifier.

that worked! I guess I need to brush up on the different arguments for figure and tabular. –  Tim Jul 9 '12 at 20:03
