How do i plot a polarpattern with 2D

Hello I need to ask about the Ambisonic b-format directional characteristics WXYZ like the picture.

W=omnidirectional

X、Y ="8" type directional

W(t) = s(t)/√2

X(t) = s(t)cosϕcosδ,

Y(t) = s(t)sinϕcosδ,

Z(t) = s(t)sinδ,

Thank you~~

There is too much missing information!

phi = randn*pi;
delta = randn*pi;

s = @(t) t;
W = @(t) s(t)./sqrt(2); 
X = @(t) s(t).*cos(phi).*cos(delta); 
Y = @(t) s(t).*sin(phi).*cos(delta); 
Z = @(t) s(t).*sin(delta);

t = linspace(0, 2*pi, 50);

figure
Pax = polaraxes;
hold on
polarplot(Pax, t, W(t))
polarplot(t, X(t))
polarplot(t, Y(t))
polarplot(t, Z(t))
hold off

Thank you so much.
