5,955766,0.160869,0.00005782,-4.07,-201.37
Basically i need to a way to tell gnuplot to ignore the first 3 rows and plot the 2rd and 3rd column.
You need to tell gnuplot that fields are delimited by commas and that it should plot columns 2 and 3:
set datafile separator comma
plot "data.csv" using 2:3 w lp
Gnuplot will ignore the first three lines automatically.
