altgraph.GraphStat — Functions providing various graph statistics

The module altgraph.GraphStat provides function that calculate graph statistics. Currently there is only one such function, more may be added later.

altgraph.GraphStat.degree_dist(graph[, limits[, bin_num[, mode]]])

Groups the number of edges per node into bin_num bins and returns the list of those bins. Every item in the result is a tuple with the center of the bin and the number of items in that bin.

When the limits argument is present it must be a tuple with the mininum and maximum number of edges that get binned (that is, when limits is (4, 10) only nodes with between 4 and 10 edges get counted.

The mode argument is used to count incoming ('inc') or outgoing ('out') edges. The default is to count the outgoing edges.
