How to plot a big network showing node ID?

Dear All,

I used plot to display a bid network with 3000 nodes. But the graph does not show the node ID. I am wondering if it is possible to plot this network with node ID when I zoom in. Here is my code:

s = edge(:,2);

t = edge(:,3);

weights = randi(1,1,length(s));

G = graph(s,t,weights);

figure = plot(G);

title('Display of the Entire Network');

xlabel('From Node ID');

ylabel('To Node ID');

When the network is small (like 20 nodes), the figure shows the node ids; but when the network is big (like 2000), it does not shows the node ids.

Thanks a lot.
