Polar plots Matlab vs Octave/Gnuplot?

[John Utz]

Hi folks;

this code :

circle = -pi:2*pi/200:pi;
polar(circle, ones(1,length(circle)),'r'); 

provides a nice concentric red circle superimposed over a "bullseye" grid.

how do i get the same thing to happen in octave? I assume the problem is 
simply more gnuplot weirdness, and is probably easy to fix, but i cant 
seem to figure out what i am doing wrong...
