Method Detail

createControlChart

public static void createControlChart(Router r)

Creates a control chart for the router. A file holding the load values, and a gnuplot script are created. Then gnuplot is called and chart saved as a .png image

Parameters:

r - Router Object

createDistributionGraph

public static void createDistributionGraph(Router r)

Creates a distribution graph for the router. Load values are parsed and categorized in bins of values and results are saved to file. A gnuplot script is created and saved and gnuplot is then called to create the graph and save it to a .png file.

Parameters:

r - Router object

createMinMaxCurve

public static void createMinMaxCurve(java.util.Hashtable<java.lang.String,java.lang.Double[]> minmax,
                                     java.lang.Double maxload)

Creates the MinMax Curve for all the routers' loads. Min and max values of load are needed to define the area of the graph for gnuplot

Parameters:

minmax - The minimum value of load we got for all routers

maxload - The maximum value of load we got from all routers.
