Ploting using octave

[Shantidev Mohanty]

Hi 
I am new to use octave. I am facing problem while I am trying to use
any plot command.

This is what I am getting when I am using the 'plot' command

-------------
octave:1> plot ([1 2 3])
pine-gnuplot: not found
warning: broken pipe
warning: in /usr/local/share/octave/2.1.46/m/plot/plot.m near line 180,
column 3: 

>>> --plt-- ("plot", varargin {:});

warning: connection to external plotter (pid = 1628) lost --
warning: please try your plot command(s) again
octave:2> pine-gnuplot: not found
warning: broken pipe
warning: connection to external plotter (pid = 2168) lost --
warning: please try your plot command(s) again

octave:2>
