Figure in LaTeX

An image is inserted with \includegraphics from the graphicx package. The figure environment adds a caption and a number, and lets LaTeX place the figure wherever it fits on the page.

\begin{figure}[h]
  \centering
  \includegraphics[width=0.7\textwidth]{chart.png}
  \caption{Period as a function of pendulum length}
  \label{fig:chart}
\end{figure}

Common mistakes

• Width in pixels: give it relative to the page, e.g. 0.7\textwidth, so the figure stays within the margins.
• \label before \caption: the reference then points to the section instead of the figure.
