[ns] how to make use of xgraph utility?

Can Anyone tell me how to take graph for throughput,packet delivery,average energy,delay in ns2 from xgraph utility for a particular routing protocol say AODV.?

[ns] AODV tcl script

Hi can anyone provide me the tcl script for simulating a network having at-least 50 nodes that moves in a random way. I want to simulate the Aodv protocol and check for its pdr, throughput and energy consumption.

[ns] energy calculation

How one can determine the initial energy of a node in ns2?
