Dear Dixit,
Please try something similar to the following commands, where files
"rmsd_cplx_P1.txt"
are the regular cpptraj outputs.
#===================
set terminal pngcairo truecolor nocrop enhanced size 1600,800 font "arial
bold,22"
set yrange [0.0 : 6.0]
set xlabel "Time (ns)"
set ylabel "RMSD (angstroms)"
set output "CPLX.png"
plot 'rmsd_cplx_P1.txt' w l dt 1 title 'P1', 'rmsd_cplx_P2.txt' w l dt 1
title 'P2', 'rmsd_cplx_P3.txt' w l dt 1 title 'P3', 'rmsd_cplx_P4.txt' w l
dt 1 title 'P4'
#====================
Greeting,
Hector.
