pdflatex is unable to include ps/eps-files. In reciprocal fashion,  
normal latex is unable to include pdf-files.

The TikZ and pgf approaches offer a solution to this conundrum.

        http://www.texample.net/tikz/examples/

Unfortunately, I don't see this as a solution to your present problem  
(there is not TikZ/pgf terminal for gnuplot).

Back to the "test.tex" file ... it is intended for LaTeX picture  
environment.

I do not know if it will properly render your figure, but it is simple  
enough to try. The LaTeX commands below will produce a picture that is  
6.4x4.8 inches.

        \documentclass[onecolumn,12pt,letterpaper]{article}
        \begin{document}
          \begin{figure}
            \begin{center}
              \setlength{\unitlength}{2.54cm}
              \begin{picture}(6.4,4.8)
                \input{test.tex}
              \end{picture}
            \end{center}
            \caption{The figure's caption goes here.}
            \label{fig:label_for_ref}
          \end{figure}
        \end{document}

This works for the example "plot(1:10)", but you'll need to verify it  
works for your purposes.
