I am trying to write a report and stuck with a wide figure. My document type is PRL using revtex4.1 with two columns. I have a wide figure which consists of 8 subfigures. I am trying to place it bottom of a page but it insists to go next page. Here is code for my wide figure:
\begin{figure*}
\centering
\subfloat[s1]{\label{fig:s1}\includegraphics[width=0.20\textwidth]{s1.png}}\qquad
\subfloat[s2]{\label{fig:s2}\includegraphics[width=0.20\textwidth]{s2.png}}\qquad
\subfloat[s3]{\label{fig:s3}\includegraphics[width=0.20\textwidth]{s3.png}}\qquad
\subfloat[s4]{\label{fig:s4}\includegraphics[width=0.20\textwidth]{s4.png}}\\
\subfloat[s5]{\label{fig:s5}\includegraphics[width=0.20\textwidth]{s5.png}}\qquad
\subfloat[s6]{\label{fig:s6}\includegraphics[width=0.20\textwidth]{s6.png}}\qquad
\subfloat[s7]{\label{fig:s7}\includegraphics[width=0.20\textwidth]{s7.png}}\qquad
\subfloat[s8]{\label{fig:s8}\includegraphics[width=0.20\textwidth]{s8.png}}
\caption{\label{fig:s}Caption}
\end{figure*}
