Plot - Remove points

[Martin]

Hi,
I'm trying to plot several series of points on a same figure, and be able to
remove part of them.
I saw Matlab can do it with:
h1=plot([1 1]);
set(h1,'visible','off');

Is it possible to do something like that with Octave?
It seems 'visible' property is only available for a figure object, not for a
plot object.

Thank you

Martin
