gnuplottex is broken with tufte

[ernestum]

I am trying to include a gnuplot plot using gnuplottex like this

\begin{figure}
    \centering
    \begin{gnuplot}[terminal=cairolatex,scale=1]
        set style line 1 lt 2 lc rgb "black" lw 7 dt 1
        set style line 2 lt 2 lc rgb "gray50" lw 7 dt 2
        set style line 3 lt 2 lc rgb "gray70" lw 3 dt 1
        set size .6,.6

        set samples 400
        set border 1 behind ls 3
        set key right center invert reverse
        set xrange[0:1]

        set ylabel "propeller speed"

        offset = 0.2
        set xtics ('$t$' offset, '$t+\Delta$' 0.8) nomirror out
        set ytics ('$\omega_t$' 0, '$\omega_{t+\Delta}$' 1) scale 0
        t(x) = x > offset ? 1 : 0
        w(w0, u, iw, t) =  w0 - (iw**t - 1) * (u - w0)

        plot w(0, 1, 0.0001, x-offset) * t(x) w l t '$\omega$' ls 1, \
             t(x) w l t '$u$' ls 2

    \end{gnuplot}
    \caption{Motor step response.}
\end{figure}

When I do that in a normal article, it looks fine like this: As soon as I enter the same code in my tufte book class, the labels are off: I guess gnuplotlatex does not like to be placed in an lrbox? Is there anything I could do here?

Hmm. I think the issue should be somewhere in the definition of @tufte@float but my latex skills are too poor to figure it out right now.

Ugly ad-hoc solution for anyone that is stuck on the same problem:

1. Put your gnuplot code in a separate file
2. Add those lines at the beginning:

   set terminal cairolatex standalone color colortext
   set output '<some_filename_you_like>.tex'

3. Execute

   gnuplot <your_gnuplot_file>
   pdflatex '<some_filename_you_like>.tex

4. Include resulting .pdf in your latex file using \includegraphics.

There is an issue when using the default width for included figures. Do not use

\setkeys{Gin}{width=\linewidth}

So it is an issue with the gnuplot cairolatex terminal.
