I want to draw an analytical signal in 3D space with it's projection in imaginary-time axes, real-time axes and real-imaginary axes concurrently. when I use command plot3 and then hold on with one of the 3 axes it plot it in the front of image not in the corresponding axes

Hello there, I tried my best to make a corresponding plot code:
f0 = 6;
divs = 30;
t = 0:1/(divs*f0):1;
eixoy = 1*ones(max(size(t)));
eixox = -1*ones(max(size(t)));
eixoz = -0.2*ones(max(size(t)));
X = (1-0.5.*t).*cos(2.*pi.*f0.*t);
Y = (1-0.5.*t).*sin(2.*pi.*f0.*t);
Z = [t; X; Y];
figure
hold on;
plot3(t,X,eixox,'b');
plot3(t,eixoy,Y,'g');
plot3(eixoz,Y,X,'m');
plot3(Z(1,:),Z(2,:),Z(3,:),'k')
xlim([-0.2 1.2])
ylim([-1.2 1.2])
zlim([-1.2 1.2])
grid on;

You could use plot3() and consecutively set one of the coordinates as a constant.
data = repmat((1:10)',1,3);
plot3(data(:,1),data(:,2),data(:,3));
l = size(data,1);
hold on;
xl = get(gca,'xlim');
yl = get(gca,'ylim');
zl = get(gca,'zlim');
plot3(data(:,1),data(:,2),repmat(zl(1),l,1));
plot3(data(:,1),repmat(yl(2),l,1),data(:,3));
plot3(repmat(xl(2),l,1),data(:,2),data(:,3));
grid on;
