# Cleaning up figure placement in Beamer/minipage

I've placed three figures on the same page through the minipage option. However, it looks quite ugly right now.

\frame{
\frametitle{Various initial conditions}

% Nomenclature:
% \begin{align}
%  1-0.05(\cos [2 \pi x/L]+\sin [2 \pi x/L])\underbrace{\cos[2 \pi y/L]}_\text{Trailing term}
% \end{align}

\begin{center}
\begin{figure}[ht]

\begin{minipage}[b]{0.35\linewidth}\includegraphics[width=.65\linewidth]{/home/dnaneet/Research/Dissertation/wigner/ic/L=lambda/dftdata/L_lambda_max_1wl_zg_E_0001_Cos_profile_0}
\caption{$1-0.05(\cos [2 \pi x/L]+\sin [2 \pi x/L])\cos[2 \pi y/L]$}
\end{minipage}
\begin{minipage}[b]{0.35\linewidth}\includegraphics[width=.65\linewidth]{/home/dnaneet/Research/Dissertation/wigner/ic/L=lambda/dftdata/L_lambda_max_1wl_zg_E_0001_Sin_profile_0}
\caption{{\tiny $1 - 0.05(\cos [2 \pi x/L] + \sin [2 \pi x/L]) \sin[2 \pi y/L]$}}
\end{minipage} \\
\begin{minipage}[b]{0.35\linewidth}\includegraphics[width=.65\linewidth]{/home/dnaneet/Research/Dissertation/wigner/ic/L=lambda/dftdata/L_lambda_max_1wl_zg_E_0001_Cos_rot45_profile_0}
\caption{{\tiny $1 - 0.05(\cos [2 \pi (x+y/\sqrt{2}L)] + \sin [2 \pi (x+y/\sqrt{2}L)]) (\cos[2 \pi (x-y/\sqrt{2}L)])$}}
\end{minipage}

\end{figure}
\end{center}

}

And the figures look like:

Any suggestions on how I can clean this up? I also find that the figure caption has too many spaces between the math symbols. Whats up with that?

My preample is:

\documentclass{beamer}

\usepackage{graphicx}
\usepackage{subfigure}
\usepackage{subfig}
\usepackage{epstopdf}
\usepackage{hyperref}
\usepackage{amsmath}
\usepackage[labelformat=empty]{caption}
\usepackage{setspace}
\usepackage[T1]{fontenc}
\usepackage[super,numbers,sort&compress]{natbib}
\usepackage{caption}
% \captionsetup{labelformat=empty,labelsep=none}
% \usepackage{makeidx}
% \usepackage{sidecap}

\setbeamertemplate{footline}[page number]
\setbeamercolor{structure}{bg=yellow, fg=black}

Why are you using minipage? You also forgot one \tiny. –  Sigur Nov 14 '12 at 0:30
@Sigur because subfigure is deprecated and my adviser has asked me to use minipage with the view of publication in the future. –  drN Nov 14 '12 at 0:30
Do you really need the \caption on the slides? You can use only \includegraphics inside a tabular to align the figures. Also you are using 3 \caption command inside the same figure environment! –  Sigur Nov 14 '12 at 0:37
@Sigur Yes I need the caption to explain how the figures are different from each other. Oh ok, the three captions inside figure... thats an interesting observation! So what do I do to have my captions? –  drN Nov 14 '12 at 0:50
What do you think \begin{center} \begin{tabular}{cc} foo & foo \\ text & text \end{tabular} \end{center}? –  Sigur Nov 14 '12 at 0:52

Very nice! I'll try to incorporate this and be back in a bit! thanks! –  drN Mar 21 '13 at 13:53
