Trying the babel gnuplot the other day, I had trouble getting the results
to C-c C-c to actually materialize in the place I'd given. Taking the
example from the org-mode babel gnuplot page, (changing the location):

#+begin_src gnuplot :exports both :file omnigraphics/omnig10.png
reset

set title "Putting it All Together"

set xlabel "X"
set xrange [-15:15]
set xtics -15,2,15


set ylabel "Y"
set yrange [-15:15]
set ytics -15,2,15

f(x) = sqrt(x - 1) + 1
g(x) = x**3
h(x) = sqrt(-x - 1) + 1

plot f(x) w lp lw 1, g(x) w lp lw 1, h(x) w l lw 1
#+end_src

The system was not creating the png in the given folder. Finally it
occurred to me to look in another place where I'd previously been creating
org-mode gnuplot pngs -- and there it was! I could do C-c C-c again and
again and see new versions of the png being created each time in
yesterday's folder, i.e., not the location given with :file. So the
:file omnigraphics/omnig10.png was being blown off and org-mode internal
had remembered where I'd previously created pngs and kept creating them
there. I've tried to recreate this scenario with just the code snippet
above -- fresh (non-daemon) emacs processes, changing the :file location
each time -- and I've reproduced the problem sometimes. I've combed through
my personal init els and it's definitely nothing I'm telling it. Strange. .
