PlotSngVec

PlotSngVec(Graph, FNmPref, DescStr)

Ranks the values of the leading left singular vector of the graph adjacency matrix plots the first SngVals on a log-log chart. The function creates three new files: 1) sngVecL.<FNmPref>.plt (the plot), 2) sngVecL.<FNPref>.eps (the plotting description), and 3) sngVecL.<FNmPref>.tab (the tab separated plotting data).

Parameters:

• Graph: directed graph (input)

  A Snap.py directed graph.

• FNmPref: string (input)

  A string representing the preferred output file name.

• DescStr: string (input)

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

Return value:

• None

The following example shows how to use PlotSngVec() for TNGraph:

import snap

Graph = snap.GenRndGnm(snap.PNGraph, 100, 1000)
snap.PlotSngVec(Graph, "my_filename", "my_chart_title")
