Plotting equation of two variables

Hi, I'd appreciate some guidance/assistance plotting: y = -sin^3(theta); x = cos^3(theta) All my attempts have produced graphs slightly different than the desired result (see attachment for my graph of reference=desired result). Could it be that the desired result (my graph of reference) was created trying to plot the equation (its solutions rather) y^2/3 + x^2/3 == 1? Mathematically it appears to be similar yet could it have produced a result somewhat different?

theta = linspace(0,2*pi) ;
y = -sin(theta).^3;
x = cos(theta).^3 ;
plot(x,y)

I don't think the result is different......to get the plot shown in the image, you need to restrict the values of theta. Use axis([0 1 -1 1]) after plotting using the above code.
