When I produce a graph with PGFplots, I first test it, before importing it in my main document tex file.
I have the file tikzpicture.tikz in which the tikzpicture environment data is included, and I have the file tikzpicture_standalone.tex with the minimal content
\documentclass{article}
\usepackage{pgfplots}
\pagestyle{empty}
\begin{document}
\input{tikzpicture.tikz}
\end{document}
to 'test' the picture.
In tikzpicture.tikz I use the command \addplot{table.txt}, where table.txt is in the same directory. The testing goes fine.
When I then use the \input command to call tikzpicture.tikz in my main tex file, which is in another directory, it obviously does not work as table.txt is not in the same directory anymore. I have to use path/table.txt instead.
Changing this for all table data every time is annoying and inefficient, so I was wondering if there is a way to let the \addplot command check the local directory too, for the file table.txt. Then, I would not need to add the file paths all the time.
