MATLAB: How to change font size of bus number in graph

font sizegraph theory

I have this graph

M=[1,2;3,4;4,1;2,3]

g = graph(M(:, 1), M(:, 2));

h = plot(g);

I have attached the graph here and want to change font of bus number.

In your case

M=[1,2;3,4;4,1;2,3]
g = graph(M(:, 1), M(:, 2));
h = plot(g, 'NodeLabe', {});
t = text(h.XData,h.YData,{'1','2','3','4'},'FontSize',14);

Hi Simone,

You can change the FontSize and FontWeight of edge labels using GraphPlot Properties

In your case for example,

s = [1 1 2 2 3];
t = [2 3 3 4 4];
G = graph(s,t);
h = plot(G);
labelText = {'ABC' 'DEF' 'GHI'};
labeledge(h,[1 1 2],[2 3 3],labelText)
h.EdgeFontSize = 14;
h.EdgeFontWeight = 'Bold';

MATLAB: Select edges that connect subgraphs together

This works for your sample data set (which does not include nodes 12:14 as shown in the plot. Please test test this, I'm not a graph theory expert so there may be cases where this does not work.

M = [1 2; 2 3; 1 3; 4 5; 5 6; 6 7; 4 7;2 4; 5 7; 5 8;11 8; 8 9; 9 10; 10 11];
g = graph(M(:, 1), M(:, 2));
h = plot(g);
bcg = biconncomp(g).'; % biconnected components
[count, group] = groupcounts(bcg); % How many of each?
edgeidx = ismember(bcg, group(count==1)); % Edges with one count
g.Edges(edgeidx, 1) % Extract
ans =
  2×1 table
    EndNodes
