# Problem with outputting graphs using gnuplot and TikZ

I want to draw graph using gnuplot and TikZ with the source (this is MWE) shown below, but it didn't work for me.

\documentclass[uplatex]{jsarticle}
\usepackage{gnuplot-lua-tikz}
\begin{document}
\include{sin}
\end{document}

In this code, sin.tex is generated by this gnuplot's code:

set terminal tikz solid
set output "sin.tex"
plot sin(x)

The following image is the outcome.

However, gnuplot's plot sin(x) outputs sine curve when the terminal is aqua. Can anyone solve this probem?
