Question: I wanted to know the procedure to get Xgraph or Gnuplot from trace file.
Answer (by Mubashir Husain Rehmani, Paris, France):

As far as gnuplot is concerned, its very easy and there is no need of any
language to learn it. what you have to do is:
1. Install gnuplot in your linux (ubuntu) distribution.
2. Once you are in the directory of gnuplot, just write gnuplot at the command prompt
3. Then once you are in gnuplot command prompt then write load "Graph.p"
4. and see the graph.
