First read the main statistics notes if you haven't already.

The intent of this page is to illustrate overall trends in defacements regardless of webserver or OS platform. One aspect of that is that we have more data, since we're not restricted to when we began collecting OS and webserver data (August 1999), but restrict the time range from January 1999 to the present.

I have done away with the histogram, which apparently caused more confusion than clarity. If someone is seriously interested in histograms of the data, drop me a line, as I still produce them for internal usage. I have replaced the histograms with a min/median/max graph that is probably more meaningful to the average reader, and is easier to read in any event.
