# Using pgfplots with raw gnuplot plotting commands, is it possible to reuse tikzpictures?

I have a main.tex in which I import plots as tikzpictures with includegraphics. A typical plot looks like this

\begin{tikzpicture}
\def \dataFile {'plots/data/sample_data.dat'}

\begin{axis}
\addplot[] gnuplot [raw gnuplot] { plot \dataFile index 0 };
\end{axis}

\end{tikzpicture}


Now, I want to make a beamer presentation using the same tikzpictures. The presentation.tex file is located in a different folder entirely. I've updated my graphicspath accordingly, but when I want to include a tikzpicture, it cannot find the data file sample_data.dat, because gnuplot is being invocated in the folder of presentation.tex.

I couldn't find a way of setting the input directory to the pgfplots raw gnuplot command. Short of specifying every data file location as a full path, is there a clever way to solve this?
