Thank you, it work. I try with

xlabel "Ua"
ylabel "Ug1"
title "Ug1=f(Ua); Ug2=300V"

and the result is just what I want for now.

BTW, I never used matlab either. I choose Octave because it seemed more
logical to me to use a math program as a spreadsheet for such a work. And also
because Octave seem to have a good matlab compatibility and it can be
useful to me to learn some of Octave basis anyway.

I have one more question. Is it possible to give a title to the 6 lines I get
on the graph? something as "Ia=28 mA" for line 1 and so on until "Ia=192 mA"
for line 6.
