Please look at the following image :

These are "minimum spanning tree" (right?) of stars distributed in X (i.e.
right ascension, RA) and Y (i.e. declination, DEC). You have this for
three open clusters : IC2391, M34, M11.

Again. The minimum spanning trees in igraph are defined for graphs (=networks), not for points:

Maybe you want this:

http://en.wikipedia.org/wiki/Euclidean_minimum_spanning_tree

Do you?

This *is* what I want to do. I want to do a plot like this.

This is not an explanation, I am sorry. What is the rule to connect the dots? Maybe this is evident for people in your field, but not to me.
