评论： Voss 2022-12-12

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 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] Show all properties

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!
