How to build links between two graphs on the same figure?

Hi,

I am encountering a problem trying to simulate interdependent systems (graphs), I constructed and built two different graphs on the same figure, and now I'm trying to add interlinks (lines) between the graphs' different nodes. Could you kindly check my script below?

Thanks!

clear all;

%Edges of first Graph
s=[1 1 2 3 3 5];
t=[2 6 7 4 5 6];
%st=vertcat(s,t);

%Edges of Second Graph
e=[1 2 2 3 4 5 5 6];
r=[3 4 7 8 1 3 2 7];
%er=vertcat(e,r);



%Constructing the Graphs
h=graph(e,r);
g=graph(s,t,[]);

g.Nodes.Name={'1' '2' '3' '4' '5' '6' '7'}';

h.Nodes.Label={'source' 'target' 'Xuewei' 'Hassan' 'TAM' 'Muath' 'Alexander' 'Waseem'}';


%X and Y coordinates of two Graphs
x1 = [0 0.5 -0.5 -0.5 0.5 0 1.5];
y1 = [0 0.5 0.5 -0.5 -0.5 2 5 ];
x2=[1 1.5 0.5 0.5 1.5 2 2.5 3];
y2=[1 1.5 1.5 0 0 3 1.5 2];

%Plotting both graphs on the same figure
w=plot(g,'-dr','XData',x1,'YData',y1); 
hold on
y=plot(h,'ko--','XData',x2,'YData',y2);

% labelnode(y,[1 2 3 4 5 6 7 8],{'source' 'target','Waseem' 'Hassan','Xuewei' 'Muath','Waseem' 'Alexander'})

%Concatenation of XData and YData and add an interlink 
datah=cat(1,w.XData,w.YData);
% plot(datah(:,1),datah(:,4),'k');
datag=cat(1,y.XData,y.YData);
line(datah(:,5),datag(:,6));

Can you mark nodes on the graph you are trying to connect? You can use an image and draw lines to explain the problem.

I guess I figured it out.

node5=[datah(1,5) datag(1,6)];
node6=[datah(2,5),datag(2,6)];
plot(node5,node6);

Hi, Waseem AL Aqqad.

If your problem is only how to view these graphs together, you may proceed like this:

Create the G that is all connected. After, use subgraph to produce your g and h graphs.

I hope helped you!

Hi Luciano,

Thanks for your reply!

My mistake was not arranging the coordinates correctly
