Digraph node label threshold

For (di)graphs with greater than 100 nodes the nodes are no longer labeled when plotted. Is there a way to change this threshold? Force labeling?

Is there a way to change this threshold?

No.

Force labeling?

Yes.

D = digraph(sprand(150, 150, 0.1));
h = plot(D); % No labels

figure
h = plot(D);
h.NodeLabelMode = 'auto';

Or if you want to label only a few nodes see the labelnode function.

figure
h = plot(D);
nodesToLabel = 1:30:numnodes(D);
labelnode(h, nodesToLabel, string(nodesToLabel))
