Dear RJ,

I am new to Xgraph. Can not give examples because I use gnuplot.

Seriously... ns-3 is a network simulator, Xgraph is a plotting tool. In between there's a whole world. You didn't say what simulation you're trying to do, what numbers you're planning to find, and so on.

Examples ? None. You first have to decide what you want to plot. Then check the ns-3 manual (there's a manual !), and in particular this link: http://www.nsnam.org/docs/manual/html/data-collection-helpers.html

Gnuplot data can be used for Xgraph as well (if I'm right), so...

But first... decide what you want to plot ! It's not like the numbers will come out of the simulation by magic, you need to decide what you want to record. And add probes to get the data.

Hope this helps,

T.

Hi,

gnuplot has an extensive manual here: http://www.gnuplot.info

In order to plot data, usually you first put the data in a file, organised in 2 columns (for the simplest graph), where the first column is the X and the second column is the Y point coordinated (time and value, for example).

The data have to be separated by one or more blank characters (spaces or tabs).

The file have to be a simple text file.

Then you open gnuplot and, assuming that your data are in a file named "data.txt", you give gnuplot the command plot "data.txt"

However, this is the ns-3 user group discussion, not the gnuplot one...

Hence, please, Read The [...] Manual !
