In the example below, how can I change (say, increase) the spacing between the labels and the floats? I tried tweaking the capbesidesep parameter, but it seems to have no effect. Thanks and regards, Jorge.
Example:
\documentclass{article}
\usepackage{floatrow}
\newlength\mysep \setlength\mysep{1cm}
\DeclareFloatSeparators{mysep}{\hskip\mysep}
\floatsetup[figure]{style=plain,subcapbesideposition=top,capbesidesep=mysep}
\usepackage{subfig}
\usepackage{graphicx}
\begin{document}
\begin{figure}
\centering
\sidesubfloat[]{\includegraphics[scale=0.25]{example-image-a}}
\\
\vspace{1cm}
\sidesubfloat[]{\includegraphics[scale=0.25]{example-image-b}}
\end{figure}
\end{document}
