[ns] need help regarding, monitoring a link from one to another node

[muralikrishna g]

hi to all..

1) here i have to get a xgraph for the link from one node to another node..
i have to get graph time vs traffic over the link, like
 n1--n2--n3--n4
how to get xgraph for the link n1 to n4

i know how to get a graph for the amount of traffic received by a node over
the time..
but

2) i dont know how to get xgraph for the amount traffic passed through the
node..

please help me regarding the above two queries.. please respond i am in need

thanks in advance
