Adding multiple labels to a graph

I have the following graph:

s = [1 2 3 4 6 7 8 10];
t = [3 3 4 5 7 5 9 11];
G = digraph(s,t);
h = plot(G);

and want to add the following labels to the nodes

schedule = [0 0 1 2 3 1 2 2 3 2 3];

I am struggling to manage this with my basic Matlab knowledge. I want to display the node numbers (here: [1:1:11]) and the corresponding values from the schedule array.

s = [1 2 3 4 6 7 8 10];
t = [3 3 4 5 7 5 9 11];
G = digraph(s,t);
h = plot(G);

% schedule = [0 0 1 2 3 1 2 2 3 2 3];
yd = get(h,'YData');
schedule = max(yd)-min(yd)-yd+1

schedule = 1×11

0 0 1 2 3 1 2 2 3 2 3

text(get(h,'XData')-0.1,yd,string(schedule), ...
    'HorizontalAlignment','right', ...
    'EdgeColor','k', ...
    'FontSize',8)

You did a great job, thanks a lot!

But unfortunately this is not the desired result...

My plan is to dynamically write the values from the schedule array to the respective nodes. The graph remains the same each time, the schedule array may change and contain different values depending on the algorithm (e.g. to illustrate the ASAP and ALAP algorithm).

Ah, ok. In that case, use schedule as you want to define it:

s = [1 2 3 4 6 7 8 10];
t = [3 3 4 5 7 5 9 11];
G = digraph(s,t);
h = plot(G);

schedule = [0 0 1 2 3 1 2 2 3 2 3];
yd = get(h,'YData');

and return handles to the text objects (t) for subsequent modification:

t = text(get(h,'XData')-0.1,yd,string(schedule), ...
    'HorizontalAlignment','right', ...
    'EdgeColor','k', ...
    'FontSize',8);

% this line is just for demo (to show two plots simultaneously), you don't need it:
copyobj(gca(),figure())

Then you can modify the text strings for new values of schedule as needed:

new_schedule = [9 19 29 21 33 11 2 62 53 42 33];
for ii = 1:numel(t)
    set(t(ii),'String',new_schedule(ii));
end

Thank you so much! This is exactly what I wanted to do!

You're welcome!

% You can use nodenames propertiest of digraph. However the names must be unique 

s = [1 2 3 4 6 7 8 10];
t = [3 3 4 5 7 5 9 11];

weights = ones(1,8);
names = {'A' 'B'  'C'  'D'  'E'  'F'  'G 4'  'H 5' '1' '2' '3'};
G = digraph(s,t,weights,names)

G = 
  digraph with properties:

    Edges: [8×2 table]
    Nodes: [11×1 table]

h = plot(G)

h = 
  GraphPlot with properties:

     NodeColor: [0 0.4470 0.7410]
    MarkerSize: 4
        Marker: 'o'
     EdgeColor: [0 0.4470 0.7410]
     LineWidth: 0.5000
     LineStyle: '-'
     NodeLabel: {'A'  'B'  'C'  'D'  'E'  'F'  'G 4'  'H 5'  '1'  '2'  '3'}
     EdgeLabel: {}
         XData: [1 2 1.5000 1.5000 2 2.5000 2.5000 3.5000 3.5000 4.5000 4.5000]
         YData: [4 4 3 2 1 3 2 2 1 2 1]
         ZData: [0 0 0 0 0 0 0 0 0 0 0]

Thanks for the answer, Maik.

I think my problem was misunderstood. I want as a result a graph with several labels at the nodes, so something like here:

Thanks in advance!
