I want to draw a graph using circular layout with some nodes inside a circular layout.

s = [2 3 4 7 8];

t = [1 6 7 8 5];

G = graph(s,t);

plot(G,'Layout','circle','Center',7)

This code gives:

I want both nodes 7 and 8 inside.

How can this be done.

s = [2     3     4     7     8];
t = [1     6     7     8     5];
G = graph(s,t);
% Remove node 8 from gra[h
G1 = rmnode(G, 8);
figure;
h1 = plot(G1,'Layout','circle','Center',7);

figure; 
h2 = plot(G);

h2.XData = [h1.XData(1:6) h1.XData(7)+[-.1 .1]];   % Node 7 & 8 around centre
h2.YData = [h1.YData(1:7) h1.YData(7)];

Thank you very much !!!!!. I would like to put one more question here.

How to change the labelling in clockwise direction?.

Presently it is {1 2 5 4 3 6} , I want this to be {1 2 3 4 5 6} in clockwise direction.

I think the layout function in MATLAB has no such option. You have to manually set the node position.

s = [2     3     4     7     8];
t = [1     6     7     8     5];
G = graph(s,t);
h1 = plot(G,'Layout','circle','Center',7);
h1.XData = [cosd(90-(0:5)*60) 0.1 -0.1];
h1.YData = [sind(90-(0:5)*60) 0 0];
axis equal
