Hey Maxi:

This is very strange, because when I execute

th = (0:0.01:1) * 2 * %pi;
clf;
polarplot(th, sin(2 * th));
polarplot(th(1:5:$), cos(2 * th(1:5:$)));

I get two polar plots, nicely superimposed one atop the other.  (Scilab, 
by default, always superimposes graphs -- you have to explicitly use the 
'clf' function if you want to start out fresh -- it's sort of the 
"anti-hold".  Fortunately, you can always do it -- in Scilab, calling 
'clf' when there are no graphics entities creates one.)
