How to use gnuplottex?

Question

I want to use gnuplottex, but even example from documentation don't work.

\documentclass[a4paper]{article}

    \usepackage{gnuplottex}
    \begin{document}
    \begin{figure}%
        \centering%
        \begin{gnuplot}[terminal=latex, terminaloptions=rotate]
            set key box top left
            set key width 4
            set sample 1000
            set xr [-5:5]
            set yr [-1:1]
            set xlabel ’$x$-label’
            set ylabel ’$y$-label’
            plot sin(x) w l lc 1 t ’$\sin(x)$’,\cos(x) w l lc 2 t ’$\cos(x)$’,\
            tan(x) w l lc 3 t ’$\tan(x)$’,\
            tanh(x) w l lc 4 t ’$\tanh(x)$’
        \end{gnuplot}
        \caption{This is a simple example using the latex-terminal.}%

I wrote pdflatex.exe --shell-escape foo.tex and use true example but errors there is I got that errors.I got error about .gnuploterrors even if wrote nothing.

I put --shell-escape but it didn't take any effect.

Answer 1

Inspecting the ' quotes in the OP they seem to be wrong. I replaced them using ordinary ASCII ' quote characters.

In addition, --shell-escape must be enabled, i.e. run pdflatex --shell-escape foo.tex
