# Script: logplot.py
# Purpose: use GnuPlot to plot two columns from a LAMMPS log file
# Syntax: logplot.py log.lammps X Y
# log.lammps = LAMMPS log file
# X,Y = plot Y versus X where X,Y are thermo keywords
# once plot appears, you are in Python interpreter, type C-D to exit
# Author: Steve Plimpton (Sandia), sjplimp at sandia.gov
