Writing a paper

Figures and images

Insert images with graphicx, size them to the column, add captions and refer to them.

A figure with a caption

Load graphicx and put the image in a figure environment. Always give it a width — width=\linewidth fits the column (or the page in figure*). Without a width the image is placed at its natural size and can run over the text; CiteTeX warns you when that happens.

\begin{figure}[t]
  \centering
  \includegraphics[width=\linewidth]{figures/results.png}
  \caption{Accuracy on the test set.}
  \label{fig:results}
\end{figure}

As Figure~\ref{fig:results} shows, …

Where the figure goes

Figures float: LaTeX places them where they fit best. The option [t] asks for the top of a page, [h] for "here", [b] for the bottom. Refer to figures by their label instead of writing "the figure below".

Side by side

With subcaption, two images can share one figure, each with its own sub-caption.

\begin{figure}[t]
  \centering
  \begin{subfigure}{0.48\linewidth}
    \includegraphics[width=\linewidth]{figures/a.png}
    \caption{Before}
  \end{subfigure}\hfill
  \begin{subfigure}{0.48\linewidth}
    \includegraphics[width=\linewidth]{figures/b.png}
    \caption{After}
  \end{subfigure}
  \caption{Denoising result.}
\end{figure}
