Re: [ns] XGraph

[Mohamed_K_Ahmed/IST/UNO/UNEBR@unomail.unomaha.edu]

Thanx Tarik for replying , I had a better solution for this problem ( I see it
is useful and easier than awk that I found very confusing), I used the vi editor
commands to adjust the file, and it was so easy
Also I think that the xgraph is a very useful plotting program to use, but I
have a comment, that why only two columns at each time??
I think it will be more useful if it had multiple columns and can be plotted at
the same time (you know, like MS Excel)
Right now I am in the plotting part of the different simulations, but I have a
simple question for you...
How can I define the step time of the simulation?
The problem is I run my simulation with 20 nodes and for 200 seconds,
the stpe is already specified (till now I don't know where), it creates
a HUGE data file....I need to increase the step size or increase the
period that the simulator gets data with

Please advice

the format for xgraph is pretty simple : 2 columns of text entries. left column
goes on the x axis, right column goes on the y axis.

as for converting .tr to .xg, well it certainly depends on what it is you'd want
to trace. Perl or Awk can be using for processing the file and output data in
the xgraph format.
