Gnuplottex: Pass latex command to gnuplot script

0

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?

  Sure, it works great, no question. But I want to be able to use plot datapath'/data.csv' using 1:2 with lines instead of plot './ZZZ/data.csv' using 1:2 with lines. But how can I pass and expand the value of datapath inside the gnuplot document or store the content of datapath in a variable inside the gnuplot script as done in the post I linked to in my question?

  See stackoverflow.com/q/12328603/923955 I guess you need to do renewcommand{gnuplotexe}{gnuplot -e "dirname=./ZZZ"} and use dirname in the script file. I don't know about quoting, though, perhaps you don't need them.

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}

  That exactly is my question. In this post the value of the line color is stored in a macro and expanded into a variable s inside the gnuplot script without writing it. So I guess it is possible. I just wasn't able to modify the approach to my problem. I always get the error that the files cannot be found.

  This would require modifying the gnuplottex source code to read and replace a macro in the file.
