Agreed. Thats what the spreadsheet I replaced did. Its readable enough, 
and the reduced row height is valuable enough for the tool's overall 
usability to offset any perceived difficulty on reading the rotated text.

Yes, I can always do that if push comes to shove, but I thought I'd first 
try converting that into a method that generates a derived Font that I 
can simply hand to my class, which is derived from JLabel, via its 
setFont() method.

Unfortunately that would be a non-starter: each column has a couple of 
rows on control totals above the names, then the names, and below that 
the matrix used to visualise the overall current state of the roster. As 
some of the name lists contain over 25 names and the matrix has  a date, 
then up to four roster slots to the left of the matrix (and Murphy says 
that of course the roster with the most slots per day also has the 
biggest list of people to be rostered, all columns must be as narrow as 
possible or I ending up scrolling sideways as well as up and down, this 
would make an already difficult rostering job that much harder.

Good point. I'm currently using a Monospaced plain 10 point text which 
seems quite readable. I've already modified your code to use this font 
and the readability is pretty good - even "[NA]" looks OK.
