Re: [Gnuplot-info] epslatex outputs into different directories sometimes

[<mw...@gm...>]

Hi,

Sorry for the delay. The problem was: With epslatex terminal (and possibly other terms too) using 'cd' between 'set output ...' and 'plot ..' is broken. (see <http://sourceforge.net/mailarchive/forum.php?thread_name=20071119141314.119800%40gmx.net&forum_name=gnuplot-info>)

The reason is that 'set output ...' opens the outputfile whereas the plot command opens the secondary outputfile via 'EPSLATEX_reopen_output()'.

In my opinion the best would be to open the 1st output file during the 'plot' command, but I don't know about gnuplot internals and can imagine that this is impossible.

What about saving the current working directory in the call of term_set_output and (temporarily) reset the path  in EPSLATEX_reopen_output while the 2nd file is created.
