I see screenshots and I see that all commands are illegible.
You are sending jpeg pictures which use lossy compression and are simply 
inadequate for the purpose of deducting which commands you used.

For the resulting gnuplot graphs, it's ok. But the commands are illegible.
Simple copy&paste into a plain-text email does the job.

you should take this to the gnuplot mailing list. Printing this way is 
not done by octave, but by gnuplot. Also copy&paste is done by gnuplot, 
not octave. So I suggest you ask the gnuplot list.

 From your original email I see that you are using verison 3.0.2
Have you tried using a more recent version yet and see if the problems 
are still present?

Using a 3.2.0 version I can do

 > h = plot(rand(4))
h =

   -5.4457
   -4.9885
   -3.1659
   -2.1473

 > set(h(3),"linewidth",4);
 > set(h(4),"linewidth",7);
 > get(h(1),"linestyle")
ans = -
 > set(h(1),"marker","+");

and I get what I expect.

The same goes for version 3.0.5

What currently will *not* work is changing the linestyle. This seems to 
be broken (according to a comment found in __go_draw_axes__.m).
Maybe Ben Abbott can comment on that.
