plot() command does not work

[Isaac Lorencez]

Hi,

I've installed octave 3.2.4 on a windows xp system and when I try:

 

octave:2> t = linspace (0, 1.0, 50)';
octave:3> x = sin(t)
octave:4> plot (t,x);
warning: isstr is obsolete and will be removed from a future version of Octave, please use ischar instead

octave:5>

 

No plot is shown, nothing happens. What is the problem? There were no installation problems.

 

Regards,

Isaac
