Have a look at the overpic package, and use pict2e for more control over
drawing lines and things.

\usepackage{overpic}
\usepackage{pict2e}

See appended tested document. Alternatively, just put the legend-drawing
bits in a picture environment and, for example, put the figure in one
row of a tabular environment and the picture in the next row. I'd prefer
overpic because you can place the legend anywhere, including inside your
plot.

==================

\documentclass{article}

\usepackage{graphicx}
\usepackage{overpic}
\usepackage{pict2e}
\usepackage{color}

\begin{document}

Hello

\begin{figure}[h]
\begin{center}
\begin{overpic}[grid,width=0.5\textwidth]{graphic-file-here}
  \put(0, -5){\color{red}{\line(1,0){20}}\quad apples}
  \put(0, -10){\color{blue}{\line(1,0){20}}\quad pears}
\end{overpic}
\vspace{5ex}  
% this is a kludge because I've put the text outside the figure
% The result from overpic will always occupy the space of the
% graphic only, not the picture elements.
\end{center}
\caption{How does this look?}
\end{figure}

Goodbye
