search path does not include the path of the figure file

[nschloe]

When using

table {data.dat};

the search path for data.dat includes ., the directory of the main TeX file. In many cases, the figure file is itself input from another directory, ./figures/ or so. In this case, one has to add

table [search path=./figures/] {data.dat};

That is unfortunate since now, the figure code depends on where it is included from.

It'd be great if the default search path included the directory of the file from where it was directly included.

Yes, pgfplots does not search the input path (which should be fixed), but if you use \input LaTeX does not update \input@path and therefore pgfplots can't know from where a figure is input. So you'll need the import package and use

\import{figures/}{plot.tex}

instead of

\input{figures/plot.tex}

Ad hoc workaround (probably misses corner cases)
