I have a figure illustrating a 3-step process, for which I use subfigures. The desired output is something like this (excuse my paint skills):
Now the placement of the subfigures/images is achievable using minipages or multicolumn:
\begin{figure}
\begin{minipage}[c][8cm][c]{0.5\textwidth}
\centering
\vspace*{\fill}
\includegraphics[height=3cm]{step1}
\subcaption{Step 1}
\label{fig:process11}
\includegraphics[height=3cm]{step3}
\subcaption{Step 3}
\label{fig:process13}
\end{minipage}
\begin{minipage}[c][8cm][t]{0.5\textwidth}
\vspace*{\fill}
\centering
\includegraphics[height=7cm]{step2}
\subcaption{Step 2}
\label{fig:process12}
\end{minipage}
\caption{Process 1}
\label{fig:process1}
\end{figure}
However, that causes step 2 to have the c number and step 3 to have the b number. How can I fix the numbering?
