Degree centrality over time

Now, you're going to plot the degree centrality distribution over time. Remember that the ECDF function will be provided, so you won't have to implement it.

Exercise instructions

  • Create a list of degree centrality scores month-by-month. To do this:
    • In each iteration of the first for loop, compute the degree centrality of G using the nx.degree_centrality() function. Save the result as cent.
    • Append cent to the list cents.
  • Plot ECDFs over time. To do this:
    • Iterate over range(len(cents)) using a for loop. Inside the loop, use the ECDF() function with cents[i].values() as the argument. Unpack the output of this into x and y.
    • Pass x and y as arguments to plt.plot().

Hands-on interactive exercise

Have a go at this exercise by completing this sample code.

# Import necessary modules
import networkx as nx
import matplotlib.pyplot as plt

# Create a list of degree centrality scores month-by-month
cents = []
for G in Gs:
    cent = ____
    ____


# Plot ECDFs over time
fig = plt.figure()
for i in ____:
    ____, ____ = ____ 
    plt.plot(____, ____, label='Month {0}'.format(i+1)) 
plt.legend()   
plt.show()
