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. (I did updated emacs-w3m from cvs the other day, so I suppose thats another possible source of error, but it seems unlikely). I agree that it appears that the table data being handed to gnuplot from org-mode is somehow being formatted in a way that gnuplot does not understand.
