Displaying node name in a network graph

Hello All,

I seem to have an issue in displaying the node names. My code goes as follows:

density=0.001
names = 1:295;
node_names=reshape(cellstr(num2str(names(:))),* size(names)); %%assigning node names

A = sprand( 295, 295, density );%%creating  sparse random adjacency matrix

A=tril(A,-1);

A=A+A.';

G =graph(A,node_names);

ax=axesm('mercator','MapLatLimit',[40 41],'MapLonLimit',[-74 -73]);

setm(gca, 'origin',[-74.900,-73.750,-73.5340])

p=plot(ax,G);

Thanks in advance

is this possible to implement......for PEG algorithm

I think that it doesn't label them by default when the number of nodes gets bigger than some number. You can tell it that you really do want them by using the labelnode function.

labelnode(p,names,node_names)

It does get a bit "busy" though.

Thanks! once again :)

you can try plot(G,'NodeLabelMode','auto') as well
