latex图排版指南

单图

\begin{figure}[h]
  \centering
  % Requires \usepackage{graphicx}
  \includegraphics[width=4cm,height=6.2cm]{picture//FP-growth4.png} \\
  \caption{条件模式基}\label{FP4}
\end{figure}

一排多图

\begin{figure}[htbp]
\centering
\subfigure[资讯]{         % 定义小图
\begin{minipage}[t]{0.5\linewidth}    %图占行宽比例
\centering
\includegraphics[width=7cm,height=5.7cm]{picture//content.png}  %定义长宽
%\caption{fig1}           %小图标题
\end{minipage}%
}%
\subfigure[商城]{
\begin{minipage}[t]{0.5\linewidth}
\centering
\includegraphics[width=7cm,height=5.7cm]{picture//mall.png}
%\caption{fig2}
\end{minipage}%
}%
\centering
\caption{对比图}               % 整个图的标题
\end{figure}

多排多图

方法一：换排加回车键

\begin{figure}[htbp]
\centering

\subfigure[资讯]{        
\begin{minipage}[t]{0.5\linewidth}    
\centering
\includegraphics[width=7cm,height=5.7cm]{picture//content.png} 
%\caption{fig1}          
\end{minipage}%
}%
\subfigure[商城]{
\begin{minipage}[t]{0.5\linewidth}
\centering
\includegraphics[width=7cm,height=5.7cm]{picture//mall.png}
%\caption{fig2}
\end{minipage}%
}%
                 %这个回车键很重要 \quad也可以
\subfigure[资讯]{        
\begin{minipage}[t]{0.5\linewidth}   
\centering
\includegraphics[width=7cm,height=5.7cm]{picture//content.png}  
%\caption{fig1}          
\end{minipage}%
}%
\subfigure[商城]{
\begin{minipage}[t]{0.5\linewidth}
\centering
\includegraphics[width=7cm,height=5.7cm]{picture//mall.png}
%\caption{fig2}
\end{minipage}%
}%

\centering
\caption{ pics}
\end{figure}

方法二：图与图之间加\quad
此法更简洁

\begin{figure}[htbp]
\centering
\subfigure[pic1.]{
\includegraphics[width=7cm,height=5.7cm]{picture//mall.png}
%\caption{fig1}
}
\quad
\subfigure[pic2.]{
\includegraphics[width=7cm,height=5.7cm]{picture//mall.png}
}
\quad
\subfigure[pic3.]{
\includegraphics[width=7cm,height=5.7cm]{picture//mall.png}
}
\quad
\subfigure[pic4.]{
\includegraphics[width=7cm,height=5.7cm]{picture//mall.png}
}
\caption{ pics}
\end{figure}

排版有问题，可以调整宽度
