:mod:`altgraph.GraphStat` --- Functions providing various graph statistics
==========================================================================
.. module:: altgraph.GraphStat
:synopsis: Functions providing various graph statistics
The module :mod:`altgraph.GraphStat` provides function that calculate
graph statistics. Currently there is only one such function, more may
be added later.
.. function:: 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.
