# Problems with Gnuplot

I am a begineer in LaTex and absoulte novice in gnuplot. I am using Texstudio and Windows 8.1. The problem is - I cannot make LaTex display a simple image. Probably some settings issue. In paricular, I took the simplest gnuplot code from the web (with slight adjustment):

This is the gnuplot code for my graph:

reset
set key inside left top vertical Right noreverse enhanced autotitles box linetype -1 linewidth 1.000
set samples 50, 50
plot [-10:10] sin(x),atan(x),cos(atan(x))
set term pslatex auxfile
set output 'proba1.tex'
replot


This is a file (test1.tex) that I get (besides ps file):

\put(660,400){\makebox(0,0)[r]{\strut{}-1.5}}%

This is LaTex text:

\documentclass[11pt,twoside,a4paper]{article}
\usepackage{graphicx}
\begin{document}
gnuplot test
\begin {figure}
\begin{center}
\input{test1.tex}

\end{document}


It might seems silly, but I am looking for the solution for days now, but no luck. Many thanks. Marko

• Your file test1.tex is incomplete, i.e. missing lines from the end. Is that really what you get from gnuplot? – mvkorpel Jul 4 '14 at 14:42
• With this setup you have to compile along latex+dvips+ps2pdf – egreg Jul 4 '14 at 14:46
• Ok, I hate to answer questions with questions, but do you mind me asking why not set teminal latex? It saves you lots of headaches. – Pouya Jul 4 '14 at 15:16
• I have a revolutionary (;-)) proposition: Why output gnuplot to LaTeX instead of eps or pdf directly? (Special cases, when special characters needed-> use latex terminal, otherwise postscript enhanced or pdf terminal) – user31729 Jul 4 '14 at 16:36
• Hi, thank you for your comments are prompt asnwers. Few lines were missing, I added those now. But there are some weird characters there, in notepad++ those empty spaces shows as NUL. About latex+dvips+ps2pdf compiling, LaTex gives me errors (text line contains invalid characters) so I cannot proceed with dvips and ps2pdf. I also tried output to eps, but again LaTex gives me errors. – Marko Jul 4 '14 at 18:17

OK, thanks to you guys I managed to find a solution: first, gnuplot did create incomplete tex file, as mvkorpel noticed. I had to write unset output in gnuplot and then I got a complete tex file. According to gnuplot FAW, some output formats must be explicitly closed like this. After that I used latex+dvips+ps2pdf` as egreg suggested. This solved the problem. Many thanks once more.
