Hello,

I have two vectors (6,1), one for X coordinates and the other for the Y coordinates. I want to use the function Graph to create a graph that join each (x(i),y(i)) in a specific way, in this case:

s=[1,2,5,5,5,5,6,6,6,6]

t=[3,4,1,2,3,4,1,2,3,4]

graph(s,t)

I don't know how to locate the vertices in my specifc coordinates, If anyone know how to do it I would be grateful.

Thank you so much.

When you call plot on your graph you can specify the X, Y, and Z coordinates of the nodes. See the "Custom Graph Node Coordinates" example on the documentation page for the plot for graph objects.

If you want to keep the graph and the coordinate data together, add the coordinates as additional attributes on the graph object.

Thank you, but my problem is that I want to create a kind of 'shortest path' optimization program so I think I need to use the Graph function instead of plot but I want every vertice in a specific coordinate position and I don't know if graph can do that.
