How do I display this image in a single column, for a 2 column paper one after the other in the centre

Question

I tried the following

\begin{center}
   \begin{figure}
    \centering
    \includegraphics[width =11cm, height = 5cm]{confusion-matrix.png}
    \caption{Confusion matrix
    }
    \label{fig:my_label}
\end{figure} 
\end{center}

but it doesn't seem to work
