How to add an edge between two nodes of two different graphs?

조회 수: 259(최근 30일)
I'm trying to connect the nodes of graph g (Blue) with the nodes of graph h (Red).
so=[1 1 1 2 2 2 2 3 3 3 5];
ta=[2 3 4 3 4 5 6 6 7 5 7];
g=graph(so,ta);
p=plot(g);
x=p.XData;
y=p.YData;
z2=[0 0 0 0 0 0 0];
subplot(2,2,1);plot(g,'XData',x,'YData',y,'ZData',z2)
s=[1 1 1 2 2 3 3 3 3 4 4 5 5 ];
t=[2 5 6 3 4 7 4 5 6 7 5 7 6 ];
h=graph(s,t);
z=[-3 -3 -3 -3 -3 -3 -3];
hold on; subplot(2,2,1);plot(h,'XData',x,'YData',y,'ZData',z)
Is it something doable?
Thank you all for your continuous support!

You could also add the edges of both graphs to one larger graph, and then use addedge to connect them. You would probably not get a clear separation visually of what used to be the first graph and the second graph this way, though.
so=[1 1 1 2 2 2 2 3 3 3 5];
ta=[2 3 4 3 4 5 6 6 7 5 7];
g=graph(so,ta);
p=plot(g);
x=p.XData;
y=p.YData;
z2=[0 0 0 0 0 0 0];
s=[1 1 1 2 2 3 3 3 3 4 4 5 5 ];
t=[2 5 6 3 4 7 4 5 6 7 5 7 6 ];
h=graph(s,t);
z=[-3 -3 -3 -3 -3 -3 -3];
gh = graph([so, s+7], [ta, t+7])
gh = addedge(gh, 2, 4+7)
plot(gh,'XData',[x, x],'YData',[y, y],'ZData',[z2, z2-3])

OMG! I wonder when can I reach this level of creativity.
Very interesting small examples indeed. I will start practicing and learning from here.
Thanks for your time and continuous support!

v1=[x(1) x(1)];
v2=[y(1) y(1)];
v3=[z2(1) z(1)];
j1=[x(2) x(4)];
j2=[y(2) y(4)];
j3=[z2(2) z(4)];
line(v1,v2,v3,'Color','red','LineStyle','--')
line(j1,j2,j3,'Color','red','LineStyle','--')

It's not possible to add an edge between nodes of different graphs. So, this is the only way, I guess, to visualize an interlink between nodes of different graph. It might be inefficient though especially for larger number of nodes.
