#2184 — help sought with cairolatex terminal

My first baby steps with LaTeX and this gnuplot script:

set output 'gnuplotout.tex'
set terminal cairolatex pdf size 3, 3
set title 'this is the first' font "Arial Bold, 14"
set xlabel 'Hello x'
set ylabel 'hello y'

plot sin(x), cos(x)

unset out

Then my LaTeX document. (I did put the required packages in the pre-able).

\begin{figure}
\input{gnuplotout.tex}
\includegraphics[scale=1]{gnuplotout.pdf}
\end{figure}

The latex compiler complains about two things:

1. It cannot find the 'gnuplotout.tex' file.
2. There is no BoundingBox in the pdf file.

Yet the dvi output does contain all the text (not the graph). A pdf 
version (by dvipdfm) contains both although offset from each other.

Any help much appreciated...

Your main problem is latex's failure to find the file. 
But there are other things you will need to deal with.

The documentation for cairolatex says that the text 
and font are handled by latex, so you need to use 
latex's font selection syntax. 

There is no Arial support in my version of TeX, so the 
following example uses Helvetica. I experimented with 
various things and settled on

  set terminal cairolatex pdf size 3, 3 font "phv, 12" 
  set title '\large\textbf{this is the first}' font ",14"

Then my test file contains:

  \documentclass[12pt]{article}
  \usepackage{graphicx}
  \usepackage[T1]{fontenc}
  \begin{document}

  \input gnuplotout

  \end{document}

Note that cairolatex terminal does not seem to pass the size 
part of the font options to the output, and uses them only 
for spacing purposes. The gnuplotout.tex file contain 
  \fontfamily{phv}\selectfont 
which switches to Helvetica, but there is no size switch. 
Hence the 12pt class option in the tex document file to get 
12pt in the normal text, and the \large command to get 14pt 
in the title.

Only \input{gnuplotout.tex} is to be used. That file already 
contains the actual \includegraphics command.

If you are using a PDF figure, you need to be compiling with 
pdflatex, and there should be no .dvi file, only a .pdf.

As for finding the file, see if you can locate it yourself 
(along with gnuplotout.pdf) and move both to the directory 
where you are processing your document file.

Thanks,

pdflatex did it. All is well now. I learned something along the way!
