How to vertically align 3 images with subfigure?

(4 answers)

Closed 9 years ago.

I want to position 3 images side by side. Actually I am doing like this, but they don't get side by side (see the pic on the bottom). Also is there any way to show only 1 caption for these 3 figures?

\begin{figure}[ht]


\begin{minipage}[b]{0.3\linewidth}
\centering
\includegraphics[scale=1]{i/houghtrain.png}
\caption{default}
\label{fig:figure1}
\end{minipage}

\hspace{0.3cm}


\begin{minipage}[b]{0.4\linewidth}
\centering
\includegraphics[width=\textwidth]{i/houghframe.png}
\caption{default}
\label{fig:figure2}
\end{minipage}

\hspace{0.3cm}

\begin{minipage}[b]{0.4\linewidth}
\centering
\includegraphics[width=\textwidth]{i/houghspace.png}
\caption{default}
\label{fig:figure3}
\end{minipage}
\end{figure}

They are not good positioned:

We can go outside the margin of the document if it is needed

Answer 1

If you just want three images side by side they can be positioned just as you would position three letters or boxes, no need for minipage wrappers etc. I also added p to your optional argument as not having it makes it more likely the float will go to the end of the document.
