I want to make my subfigures bigger and keep them on the same line. Is there any way to increase the textwidth for the figure? Or are there any other ways to do this? Thanks in advance.
\begin{figure}[h]
\centering
\begin{subfigure}{0.49\textwidth}
\centering
\caption{Annual Return}
\includegraphics[width=\textwidth]{return.png}
\end{subfigure}
\begin{subfigure}{0.49\textwidth}
\centering
\caption{Annual Volatility}
\includegraphics[width=\textwidth]{volatility.png}
\end{subfigure}
\end{figure}

\centeringinstructions inside thesubfigureenvironments are redundant. – Mico Aug 11 '20 at 08:29
