Re: [igraph] how to plot degree distribution, please?

2016-09-18 Thread Tamas Nepusz
You have imported plot() from Matplotlib, not from igraph. You need to
import igraph's plot() function:

>>> from igraph import plot
>>> plot(dd).show()

Thank you for your reply, Tamas. But when I use plot(dd), I got a type error:


BTW, i'm using python 3.5.1

__plot__ is an internal function; you are not supposed to call it
directly. Call the plot() function instead:

>>> dd = g.degree_distribution()
>>> plot(dd)

or, if the plot is not shown automatically, then:

>>> plot(dd).show()
