Hi John,

I'm not sure what Org mode is doing behind the scenes, but I suspect something is getting muddled because you specify both the src block file header /and/ the output terminal in the gnu plot code.

Perhaps a simpler solution - if you indeed want Postscript images - would be to remove the =:file …= header argument and specify the =set output= within the gnuplot script itself?  That should still generate the .eps file.

I may give this a try at work tomorrow... just tried the same file on my Mac at home (running the same linux setup) and it's working, though I still get a filename.eps and a filename-eps-converted-to.pdf output. It's just that the .eps on this computer is valid and viewable.

I'll have to dig into this some more; perhaps comparing org versions and .emacs config files.

I'm pulling from the org git repo and doing a make now on this computer as we speak. If it still works, I'll do the same at work tomorrow and see if that helps.

Fresh org pull, same file... no viable output. The =set output "test.eps"= command with no :file header does not work. I get "code block produced no output" in the minibuffer.

Here's some things of interest...

-- Removing =set terminal...= and exporting via =:file test.png= works

-- Using =set terminal postscript= and =:file test.ps= works

-- Using =set terminal postscript eps enhanced= and =:file test.eps= does *not* work

What package provides the eps ability? Perhaps I removed something from my system that I didn't intend to!

Any suggestions on how to see what's going on?

Thanks,

John

 

Thanks for the input,

I have the following gnuplot/babel block and for some reason the resultant .eps file comes up broken but a corresponding version of it gets converted to pdf somehow... what's going on? I stole an example just to check and make sure it wasn't my gnuplot code: http://t16web.lanl.gov/Kawano/gnuplot/intro/plotfunc-e.html

-----

#+begin_src gnuplot :file export.eps :exports results

reset

set terminal postscript eps color enhanced 20

a=0.25

 b=0.02

 c=0.05

 d=0.1

 f(x)=c/((x-a)*(x-a)+b)+d/sqrt(x)

 set xrange [0:1]

 set yrange [0:4]

 plot f(x)

#+end_src

I get a file export.eps which is broken and unreadable by geeqie. I get a corresponding file called export-eps-converted-to.pdf that opens fine and looks like it should.

What am I doing incorrectly?

Thanks,

John
