Hi, 
I would plot graph with same x axis and different y axis 

for an y axis I use

plot [-1:1.5][:] 'trace_300_gnu.txt' using (($1*13.60)-4.64665):(abs($6)), with lines lc rgb 'black' lw 2 lt 1 title "OO"

instead for ather y is 
plot [-1:1.5][:] 'trace_300_gnu.txt' using (($1*13.60)-4.64665):(abs($4)), with lines lc rgb 'red' lw 2 lt 1 title "OO"

my trace file is
