Hello, how could I fill a figure bounded by a curve?

I have a quite complex plot and I would like to fill with colour the bounded areas I am trying to use area(x,y) function but it doesn't work... This is my script

 if true
    % code
figure()
hold on
for i=1:(2*n)
    x=zeros(1,length(phi));
    y=x;
    r=x;
    r=r_phi0(i)*exp(b*phi);
    x=r.*cos(phi);
    y=r.*sin(phi);
    plot(x,y)
    if (i>1 && mod(i,2)==0) 
        drawLine([r_phi0(i-1) 0],[r_phi0(i) 0]);  
        if mod(N,2)==0
        drawLine([r_phiN(i-1) 0],[r_phiN(i) 0]); 
        else
        drawLine([-r_phiN(i-1) 0],[-r_phiN(i) 0]); 
        end
    end
    area(x,y)
    axis tight
end

end

This is what it plot without using area()...

thank you all.

Hello Astarita,

You can use fill function in MATLAB. All you just need is X and Y axis data for both curves. I also wrote sample code you can play with your data.

fill([X data for line1',fliplr(X data for line 2')]',[(Y data for line 1', ... fliplr((Y data for line 2)')]','required color');

Wish this code would work for my situation :(
