How not to show a label under a graph using subfloat — restart numbering of labels

Question

I have this code:

\documentclass{beamer}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage{lmodern}
\usepackage[caption=false]{subfig}

\graphicspath{{/folder/images/}}

\title{}
\author{}

\begin{document}


\begin{figure}
\centering

\subfloat[][]{\includegraphics[scale=0.5]{Graph1}}

\end{figure}

\end{document}

Under the graph it shows me a label , "a". How can I not show it? Also, how to restart numbering of labels because the subfloat numbers all the figures from the beginning of the document?

Answer 1

subfig provides a number of different inputs to its \subfloat macro. It's usage results in different captioning styles. From the subfig documentation (Table 2 of section 2.2.1 The \subfloat Command, p 4):

So, the only way to have a \subfloat without a caption is to use it as \subfloat{<stuff>} and remove both possible optional arguments.

\subfloat numbering, by default, is renewed with every figure environment. However, you can control the counter number by means of setting the subfigure counter. For example, \setcounter{subfigure}{4} will make your \subfloats be numbered from (e).
