Here's the gnuplot src for a start, but you have to add up your data
lines before giving them to gnuplot so that they will stack above each
other in the graph. Also, I think the order of writing them is
important so that they overlap in the right way [tm].
Deleting the first line of my log is currently done with sed 1d
<original.dat>temp; mv temp original.dat. Is there no better way?
