# Cut-Off Subfigure Captions

I created a figure with four subfigures (two rows of two subfigures) where each subfigure has a caption below the subfigure. Strangely, the captions for the subfigures in the top row are partially covered by the subfigures in the second row. I can't seem to figure out why that is or how to fix it. An example of the code is given below.

\begin{figure}[ht!]
\begin{center}
\subfigure[$k$~$=$~0.1]{\label{fig:1}\includegraphics[scale=0.4]{Fig1}}
\subfigure[$k$~$=$~0.5]{\label{fig:2}\includegraphics[scale=0.4]{Fig2}} \\
\subfigure[$k$~$=$~1.0]{\label{fig:3}\includegraphics[scale=0.4]{Fig3}}
\subfigure[$k$~$=$~2.0]{\label{fig:4}\includegraphics[scale=0.4]{Fig4}}
\end{center}
\caption{Plots.}
\label{fig:Figs}
\end{figure}
