I am not sure where the problem is, but using gnuplot as per the MWE below does not know about the -output-directory= option as I get

Package pgfplots Error: sorry, plot file{TeX-SE_contourtmp0.table} could not be opened.

So if you save the MWE as TeX-SE.tex, the following fails with the above error message:

mkdir tempfiles
pdflatex -shell-escape -output-directory=tempfiles TeX-SE.tex

but the following works fine

pdflatex -shell-escape  TeX-SE.tex



  \pgfmathparse{exp(-#1^2) * sin(deg(#2))}%

%% Following based on code from http://tex.stackexchange.com/questions/87674/how-to-coherently-combine-3d-and-contour-plots-with-pgfplots
    domain y=0:2*pi,

        contour gnuplot={
            output point meta=rawz,
        z filter/.code=\def\pgfmathresult{-1.6},

    \addplot3[surf,samples=25] {FunctionE(x,y)};
  • I assume that is because gnuplot doesn't know that it should also output to the tempfiles folder. So maybe it helps -- as you guess this is untested -- when you add \pgfplotsset{prefix=tempfiles/} to the preamble, to redirect the gnuplot output to that folder, too. – Stefan Pinnow Mar 13 '17 at 12:34
  • @StefanPinnow: Nope, that does not seem to do it. It seems that the TeX-SE_contourtmp0.dat and TeX-SE_contourtmp0.script files do get written to the tempfiles/ directory, but the TeX-SE_contourtmp0.table is not generated. – Peter Grill Mar 13 '17 at 12:44
  • Oh yeah, forgot that it was not simply gnuplot but contour gnuplot ... Ok, let's see, if someone else has a solution. Otherwise I will ask Christian (Feuersänger) -- the author of PGFPlots -- for a possible solution. – Stefan Pinnow Mar 13 '17 at 12:55
  • @DavidCarlisle: Had not seen that comment before. Am hoping htat mine is the 1/1000. I did not know that you could link to specfic comments like that. How do you get the url for it? – Peter Grill Mar 13 '17 at 13:11

You could try to add

  cmd= {cd tempfiles & gnuplot \"\script\"} 

to your contour gnuplot options (if you are on linux replace the & with whatever is used there to combine commands).

You could also try to find a working solution with the file and the prefix key, but imho they and --output-directory confuse each other.

Like David Carlisle in his comment I think that the best is not to use --output-directory.
