Great article! Small nitpick from someone who just tried this on his server logs :)

  * on my machine xargs -I implies -L1, so you can drop that
  * use gnuplot -p or the graphic will disappear immediately after rendering

I agree, good article.

A sort -n is also required before the uniq since server logs have the time of the request but are printed when the response is complete so they're not necessarily increasing.
