Use Xgraph with NS2

XGRAPH is a general purpose x-y data plotter with interactive buttons for panning, zooming, printing, and selecting display options. It will plot data from any number of files on the same graph and can handle unlimited data-set sizes and any number of data files.

 How to Install:
This example goes with two previous posts:
1. NS2 UDP Example
2. NS2 TCP Example

You will need both source code to plot ns2 simulations in this example.

Additionally we have to use these perl scripts to extract data from output trace generated from NS2.

I have written a shell script to do our job quickly.

Sample out put:

      # type: perl throughput.pl > output file

      #we compute how many bytes were transmitted during time interval specified by granularity parameter in seconds

      go through your out put trace files.

    Hello sir
    I am using awk scripts for plotting graphs in ns2 using awk -f abc.awk abc.tr > abc.xg
    and after that i plot graph with xgraph abc.xg
    this command displays values for single input i.e abc.xg
    Now i want to plot a graph in which i can compare values for different xg files to get the graphs shown in this blog using perl scripting.
    Please tell me how to do this with awk scripts.
    Thanks
