it's very easy in gnuplot to do that. Let us assume that you have a 
file "file.txt" with 4 columns $1 $2 $3 $4 seperated by spaces, tabs, 
...etc
you are interested to plot say the values in column $1 (y axis) versus 
the values in column $3 ( x axis) then the minimum command will be:

gnuplot>plot "file.txt" u 3:1

that's it. If they are milion points it is going to take some time for 
the plot to show up in xterm pop up window, but certainely gnuplot is 
more powerfull than Excel in plotting large sets.
I hope that helps.
