First of all, thank you for your help.

I'm trying to print two curves in the same graphic. This is the code

t = [0:0.01:0.98];
y1 = sin(8*pi*t);
y2 = cos(8*pi*t);

plot(t, y1);
hold on;
plot(t, y2);

The problem is that the second curve doesn't appear. Or if I try:

t = [0:0.01:0.98];
y1 = sin(8*pi*t);

plot(t, y1, 'r');

It doesn't show anything. I'm using octave version: 7.1.0 in a Ubuntu 20.04
based distro (bodhy linux).

If I try the same thing in other distro (Arch linux) it works!

I think that may be I'm missing some dependency, but can't figure it out what

Thank you for your help. Note: I don't speak english, sorry if I said
something wrong
