Technical notes to myself:
•	Delete any bad refs in the “original” chart (odd things happen when you delete something like Claymore.  Don’t worry!)
•	Copy chart to start a new graph
•	Make sure x-axis only tics at one day before labeling
•	Isolate the chart data (typically 3 days) in the 15 min table and add a row of legend labels at the top of selection range
•	Select data by editing chart range.  Should look like ='15Min'!$B$11377:$R$11666 which can be pasted, but only through right click, not ctrl-v
•	Annotate with bold labels; make subject line red
•	Copy and paste special, enhanced metafile, with border
•	Add day of week


Missing data comes in many flavors.  Some individual observations were blank, some #N/A, some zero.  Some hours completely omitted.  Many diversions completely unmeasured.  If it said zero, I kept it.  If it was blank, I usually turned that into a #N/A.  I've also been told that there can be issues regarding Daylight Saving Time.
