N = 4; % divides to 4 parts
N1 = 10;
a = linspace(0, 2*pi, N*10);
a1 = linspace(0,2*pi, N1*10);
r1 = 100;
r2=58;
r3=25;
x = r1*cos(a1);
y = r1*sin(a1);
x1 = r2*cos(a1);
y1 = r2*sin(a1);
x2 = r3*cos(a);
y2 = r3*sin(a);
figure(1)
plot(x, y,'k')
hold on
plot([x1(1:10:end);x(1:10:end)], [y1(1:10:end);y(1:10:end)])
hold on
x1 = r2*cos(a);
y1 = r2*sin(a);
plot(x1, y1,'r')
plot([x2(1:10:end); x1(1:10:end)], [y2(1:10:end); y1(1:10:end)])
plot(x2, y2,'b')
hold off
axis equal

Use fill(X,Y,C) to fill the polygon having X,Y coordinates, with colour defined by C.

Assign the mapped experimental values to the FaceColor property of the polygon object, which will change the polygon color. Additionally change the label of colormap by setting yticklabel using set function.
Use inputdlg(promt) which will create dialogue for user input.
Refer to the attached script.

Thank you Ayush for the help
This is exactly what I needed but there is just one problem. The figure obtained is not symmetric either all of the zones should be divided by equal distance or there should be no gap between the zones as shown in the figure attached.
I am attaching the figure EXACTLY I need and the one I am getting.
Thanks
