I want to access and plot the same data from different LaTeX documents (a paper and a beamer presentation) using gnuplottex. The data and the gnuplot script is stored at some individual position relative to the two documents. To re-use as much code as possible, I would like to define the relative path to the data in each document in a macro, here datapath.

My question is: How can I pass the value of this command to the gnuplot script? I would basically like to use the following in my MWE:

plot datapath'/data.csv' using 1:2 with lines

I did find this thread. However I was unable to modify it to my needs. Can someone help me, please?

MWE

documentclass{article}



usepackage[latin1]{inputenx}

usepackage{filecontents}

usepackage[

  miktex,    % 

  subfolder, % generated graphs in a ”gnuplottex” subfolder

  cleanup,   % Delete the .gnuplot files after conversion

]{gnuplottex}



newcommand{datapath}{./ZZZ}



begin{document}



% This is the data file to be plotted from

begin{filecontents*}{datapath/data.csv}

Col1,Col2

0,0

1,1

end{filecontents*}



% This is the gnuplot script I would like to use the value of datapath in

begin{filecontents*}{datapath/script.gnuplot}

set key autotitle columnhead

set datafile separator "," # for csv-file

plot './ZZZ/data.csv' using 1:2 with lines

end{filecontents*}



begin{figure}[htbp]

centering

gnuplotloadfile[terminal=cairolatex]{datapath/script.gnuplot}

end{figure}



end{document}

You can do it with immediatewrite instead of filecontents*:

newwritetempfile



immediateopenouttempfile=datapath/script.gnuplot

immediatewritetempfile{set key autotitle columnhead; 

set datafile separator ","; 

plot 'datapath/data.csv' using 1:2 with lines}

immediatecloseouttempfile
