Why doesn't the command "set function style lines" work?

[che6yoh]

Dear Dr. J. W. Eaton,

Thank you very much for your very prompt reply.

  >: When I use gnuplot without octave,
  >: the command "set function style something" works completely.
  >: But, when I use the command in octave, it doesn't work.
  >: The style isn't change from "points".
  >
  >Since Octave is plotting data from a temporary file instead of
  >plotting functions, you need to use the command `set data style lines'
  >instead of `set function style lines'.

I am very sorry.
This was a FAQ, wasn't it?
