Hi Everyone,
I have a digraph(directed graph) plotted and I want to extract the data of the nodes from it.
It would be great if anyone can help me with it. I tried get function but it always returns an empty matrix.
Any help is highly appreciated.
Regards,
Anurag Gupta

What "data of the nodes" do you want to retrieve? Do you want the coordinates of the plotted points?
B = graph(bucky);
h = plot(B);
X = h.XData;
Y = h.YData;
fprintf("Node 1 is located at (%f, %f)\n", X(1), Y(1))
Node 1 is located at (0.103347, -1.803899)
% Turn on the axes ticks so you can check the coordinates
ax = ancestor(h, 'axes');
ax.XTickMode = 'auto';
ax.YTickMode = 'auto';
xticks(-5:5)
% Draw lines -- X marks the spot
xline(X(1), 'r')
yline(Y(1), 'r')
