I'm following this link word by word, using the epslatex terminal way:

How can add some latex eq or symbol in gnuplot?

When I open up texworks, and run 

\documentclass{article}
\usepackage{graphicx}
\begin{document}
\input{plot.tex}
\end{document}

I'm presented with 

"! LaTeX Error: File `plot' not found.

See the LaTeX manual or LaTeX Companion for explanation.
Type  H <return>  for immediate help.
 ...                                              

l.96     \put(0,0){\includegraphics{plot}}
                                          %
? H
I could not locate the file with any of these extensions:
.png,.pdf,.jpg,.mps,.jpeg,.jbig2,.jb2,.PNG,.PDF,.JPG,.JPEG,.JBIG2,.JB2
Try typing  <return>  to proceed.
If that doesn't work, type  X <return>  to quit."

So basically it doesn't actually look for file extensions .tex? What am I missing? I have saved the .tex file in the same place as plot.tex and plot.eps. I'm fairly new to LaTex and even newer to gnuplot, so apologies if this is obvious.

  • My guess is you are compiling with pdflatex and not latex. pdflatex can handle lots of image formats but eps. latex can handle eps but not the common ones (jpg, png, etc.). I don't know how it works, but when I compile with pdflatex in ubuntu with TeXlive 2013, it runs something that converts the eps into a pdf and then uses the pdf. – Nico Feb 19 '14 at 22:02
  • Thanks for the reply. How do I compile with latex? I'm using texworks and the only options I have are pdflatex (which I was using originally using), luatex, xetex, context and bibtex. – AntiElephant Feb 19 '14 at 22:26
  • Gnuplot is able to render LaTeX symbols in an eps file as well, however that file has to be converted to pdf format and then included with pdflatex. Doing this way, the included figure problably has to be rotated by 90 degrees. Note that, this is not an option, if the symbols are too complex. –  Feb 20 '14 at 05:53
