I'm making a figure with four graphs next to each other but I want the graphs to be larger (without changing position). I don't mind giving up some of the margin for this, but how do you do this in latex? I have tried a couple of things but then the figure is not centered anymore.
Here is my code:
\begin{figure}[H]
\centering
\begin{subfigure}{.5\textwidth}
\centering
\begin{center}\includegraphics[width=1.0\linewidth]{Figures/fundvsprice.pdf}\end{center}
\vspace{-0.45cm}
\subcaption{Fundamental versus real values}\label{fig:1a}
\end{subfigure}%
\begin{subfigure}{.5\textwidth}
\centering
\begin{center}\includegraphics[width=1.0\linewidth]{Figures/fundvsprice.pdf}\end{center}
\vspace{-0.45cm}
\subcaption{Fundamental versus real values}\label{fig:1b}
\end{subfigure}%
\\
\begin{subfigure}{.5\textwidth}
\centering
\begin{center}\includegraphics[width=1.0\linewidth]{Figures/fundvsprice.pdf}\end{center}
\vspace{-0.45cm}
\subcaption{Fundamental versus real values}\label{fig:1c}
\end{subfigure}%
\begin{subfigure}{.5\textwidth}
\centering
\begin{center}\includegraphics[width=1.0\linewidth]{Figures/fundvsprice.pdf}\end{center}
\vspace{-0.45cm}
\subcaption{Fundamental versus real values}\label{fig:1d}
\end{subfigure}%
\caption{General caption.} \label{fig:1}
\end{figure}
