PlotHops

PlotHops(Graph, FNmPref, DescStr, IsDir=False, NApprox=32)

Plots the cumulative distribution of the shortest path lengths of Graph. The implementation is based on ANF (Approximate Neighborhood Function). The function creates three new files: 1) hop.<FNmPref>.plt (the commands used to create the plot), 2) hop.<FNPref>.png (the plot), and 3) hop.<FNmPref>.tab (the plotting data).

Parameters:

  • Graph: graph (input)

    A Snap.py graph or a network.

  • FNmPref: string (input)

    A string representing the preferred output file name.

  • DescStr: string (input)

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

  • IsDir: bool (input)

    Whether the input graph is directed or not.

  • NApprox: int (input)

    Number of ANF approximations, must be a multiple of eight. The larger this value is, the more accurate the distribution is.

Return value:

  • None

The following example shows how to plot the cumulative distribution of shortest path lengths for graphs of types TNGraph, TUNGraph, and TNEANet:

import snap

Graph = snap.GenRndGnm(snap.PNGraph, 100, 1000)
snap.PlotHops(Graph, "example", "Directed graph - hops", True, 1024)

UGraph = snap.GenRndGnm(snap.PUNGraph, 100, 1000)
snap.PlotHops(UGraph, "example", "Undirected graph - hops", False, 1024)

Network = snap.GenRndGnm(snap.PNEANet, 100, 1000)
snap.PlotHops(Network, "example", "Network - hops", True, 1024)
