line 0: invalid command

Dear all,

When I use "plot" command I get an error (not important I think). See the following commands

octave:6> x = [1 2; 3 4; 5 6]
x =

   1   2
   3   4
   5   6

octave:7> p1 = plot(x(:,1), x(:,2), "ro", "markersize",10, "linewidth", 3); hold on;
octave:8>
gnuplot> nset obj 1;
         ^
         line 0: invalid command

What does that mean?

 

Regards,
Mahmood
