xmgrace log lammps

Dear lammps users
How can I use xmgrace to plot columns of data from a LAMMPS log file ?

and can i specify lines (from line number 100 to 3500 for example) 

and columns for example Totel energy and steps.


please see:

there rest is really a question for a forum on xmgrace, or how about doing general data post-processing for plotting (e.g. with shell script commands, awk, perl, python, matlab, or similar).
