Hello, i have this file that is generated by some program and i use gnuplot script to plot the data in the file which contains 2 columns(X and y), the data is time,it's JUST numbers but the file is generated containing ns beside each number which refers to nano second . My question is can gnuplot plot it like this with the command plot... OR need i remove this ns? and if i need to do that..how ?

here is a sample from my data file:
572574000ns 469000ns
574547000ns 725000ns
571298000ns 517000ns
