rotate my countour plot without changing the axes

I have this plot which is fine, although, I want to rotate it 180 degrees; I tried the rotate function but get the following.

Error using rotate (line 33) H must contain axes children only.

i don't understand it. this was what i coded

Vq=griddata(x{1}(:),y{1}(:),V_m(:),X,Y);
[X,Y]=meshgrid(0:0.001:max(x{1}(:)),0:0.001:max(y{1}(:)));
f1=figure;
h=contourf(X,Y,Vq)
xlabel({'x(m)'})
ylabel({'y(m)'})
title('V-mean velocity profile')
hcb= colorbar;
title(hcb,'Velocity[m/s]')
rotate(h,[0 0 1],180)

Does anyone know how to rotate a contour plot without changing the axes please?

rotate() function documentation does not include contour objects for rotation. However, for 180-degree rotation, the following will work

contourf(rot90(Z, 2));

[Ernest Adisi]

can you show me how I include that code for my plot with contourf(X,Y,Vq)please

[Ameer Hamza]

Try this

contourf(X,Y,rot90(Vq, 2));

You can create a hgtransform group, parent the contour plot to it, and use makehgtform to create a transformation matrix that you can apply to the hgtransform group.
