When I use tikz, it always creates a new page. Anybody could help?

I was trying to insert a tex file containing the code for a tikz graph into a main tex file. However, I got a problem. The graph always stands alone in an independent page. So any words before or after the inserting command will be a page ahead or a page afterward. The tex file was automatically generated by R package "tikzDevice"

My Latex code is very simple.

\setmainfont{Microsoft Sans Serif}
\centering
\include{Plot1}
crazy
\include{Plot1}
\end{document}


My tikz tex code for the graph is as below:

\resizebox{\columnwidth}{!}{
\begin{tikzpicture}[x=1pt,y=1pt]
...
\end{tikzpicture}
}

• Please don't use \resizebox for elements that contain text, like the graph you show us in your image. See tex.stackexchange.com/questions/425453/… for other possibilities instead of \resizebox – samcarter Dec 16 '18 at 12:59
• Thank you samcarter! I would check it out! – Hanqing Wu Dec 16 '18 at 13:17

I just found the solution. I should use \input instead of \include!
