My file is so formatted

# Ver02 @ MSN
# vector orbital energy [hartree]
 Vector    1  2.000000  -1.889210D+01
 Vector    2  2.000000  -1.887116D+01

set term pngcairo enhanced
set output "eigen.png"
set encoding iso_8859_1
set xlabel "wavelength [nm]"
set ylabel "Energy"
set title "energy Ver @ MSN"
set key top right
set xrange [-10:10]

#color set
# '#000000' --> black
# '#FF0000' --> red
