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")
