I want to have 4 figures side by side and centered in my paper. I am using this code. The problem is that captions and figures are not aligned. It seems captions are in correct position, but figures are not and directed to right side. Captions are not below of the figures. I am using a double-column format.
\begin{figure*}[ht]
\centering
\begin{tabular}{cccc}
\begin{minipage}{115pt}
\centering
\includegraphics[width=180pt]{1.pdf}
\vspace{-75pt}
\caption{aaaa}
\end{minipage}
&
\begin{minipage}{115pt}
\centering
\includegraphics[width=180pt]{2.pdf}
\vspace{-75pt}
\caption{bbbb}
\end{minipage}
&
\begin{minipage}{115pt}
\centering
\includegraphics[width=180pt]{3.pdf}
\vspace{-75pt}
\caption{cccc}
\end{minipage}
&
\begin{minipage}{120pt}
\centering
\includegraphics[width=180pt]{4.pdf}
\vspace{-75pt}
\caption{dddd}
\end{minipage}
\end{tabular}
\end{figure*}
\vspace
suggests that your images have white borders around them.\centering
will have no effect and the figure will be an overfull box sticking out on the right.subcaption
package that would handle spacing for you ?
