I believe that this feature may only be available in later versions of gnuplot. I'm using gnuplot 4.4 locally and I've had no problems using gnuplot from Org-mode code blocks which I do most every day. the syntax for defining variables is fairly simple, try the following directly in the gnuplot terminal, if your gnuplot does have variable support it should graph a straight line of y=3D10 #+begin_src gnuplot a=3D10 plot a #+end_src Best -- Eric Nigel Beck writes: > John - thanks for the quick reply (and, btw, the very useful tutorial). > > I ought to have noted that the example works fine when invoked directly > from the command line, with the only change being that I move the data > into a file (mainly because I don't know the correct gnuplot syntax for > putting table data into a variable!). > > I haven't updated gnuplot since installing it, so I believe the org-mode > <-> gnuplot unfriendliness lies in some effect that a recent pull of > 7.01trans has had.
