Finding the coordinates of nodes in a plot

There are randomly positioned nodes named like 1, 2, 3 etc. in a plot and I will obtain a path from these nodes like path = [5 8 19 4]. How can I find the coordinates of each node in the path in the form

coordinates = [x y

x1 y1

x2 y2].

Thank you.

Try these codes below please;

x = linspace(0,2,20)';             
y = sin(x);
h=plot(x,y)
a=get(h,'XData');
b=get(h,'YData');

c=vertcat(a,b)

If understood your question correctly, what you are trying to achieve is to locate the points in the plotted data. If so,

a = 1:5;
b = randi(15, 1, 5);
plot(a, b,'ro-')
[x,y] = ginput(5);
