 IMPORTANT NOTE on how to read daily graphs
1. Daily Graphs are available only from Jan. 2002 onward.
2. The "Click here for todays 24 hour graph" applies to the day BELOW, and...
3. Date on graphic is date of generation, not depiction. That is, subtract one day to apply
that graph (If it says January 8, then the graph is for January 7).
