PlotKCoreNodes

PlotKCoreNodes(FNmPref, DescStr)

A graph method that plots the k-core node-size distribution: core k vs. number of nodes in k-core. The function creates three new files: 1) coreNodes.<FNmPref>.plt (the commands used to create the plot), 2) coreNodes.<FNPref>.png (the plot), and 3) coreNodes.<FNmPref>.tab (the plotting data).

Parameters:

• FNmPref: string

  A string representing the preferred output file name.

• DescStr: string

  Description of the graph. The string should be non-empty.

Return value:

• None

The following example shows how to plot the k-core node-size distribution for TNGraph, TUNGraph, and TNEANet:

import snap

Graph = snap.GenRndGnm(snap.TNGraph, 100, 1000)
Graph.PlotKCoreNodes("example", "Directed graph - k-core nodes")

UGraph = snap.GenRndGnm(snap.TUNGraph, 100, 1000)
UGraph.PlotKCoreNodes("example", "Undirected graph - k-core nodes")

Network = snap.GenRndGnm(snap.TNEANet, 100, 1000)
Graph.PlotKCoreNodes("example", "Network - k-core nodes")
