I want to have the labels a, b and c appear on left of the figures instead of bottom. The code taken from How to create subfloat figures (two in first row and one below)? is as follows
\documentclass{article}
\usepackage{mwe}
\usepackage{subfig}
\begin{document}
\begin{figure}
\begin{minipage}{.5\linewidth}
\centering
\subfloat[]{\label{main:a}\includegraphics[scale=.5]{example-image-a}}
\end{minipage}%
\begin{minipage}{.5\linewidth}
\centering
\subfloat[]{\label{main:b}\includegraphics[scale=.5]{example-image-b}}
\end{minipage}\par\medskip
\centering
\subfloat[]{\label{main:c}\includegraphics[scale=.5]{example-image-c}}
\caption{my fig}
\label{fig:main}
\end{figure}
\end{document}
How can I place the labels on left of the subfigures?
