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.

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.
