[cgiapp] Reporting Back (Dynamic Charts)

[Jason Purdy <suppressed>]

So I completed my work on the dynamic charts and thought I'd share back 
my findings.

DBD::Chart is definitely the way to go - it's very neat.  I did run into 
some problems and it was hard to debug (DBI's RaiseError and trace() 
don't really help when INSERT'ing bad data into the chart table), but 
with help from some Dumper()'s and die()'s, I was able to track it down 
to problem with one of my regex's.

I also took Cees' input about data changing and Mark's input about using 
the src attribute to wrap it up.

I put up a (hopefully) safe version of my code online so you can how I 
did it (if you're interested).  URL's below.

You know, one interesting thing about my cgiapp's these days is that 
there's about 100 lines of code before I'm actually putting any runmodes 
together, between the setup, the cgiapp_init w/ LogDispatch settings and 
an error_mode.

Another annoying thing about my web server setup is that whenever it 
writes files (logs, trace files, Storable files, etc), it's owned by the 
server process (www-data) and in mode 0600, so when I'm logged in and 
trying to read 'em, I gotta chmod it, be root, or something.  So that's 
why I have chmod's sprinkled in that code.  There's prolly a umask 
setting somewhere... just haven't gotten around to it.

Lastly, I'm trying to figure out how to have DBD::Chart enforce only 
whole numbers on the X axis (Day 27.3? ;)).  But as my dataset grows, it 
will become less of a problem.

Thanks everyone for the help and I still welcome input/advice. :)
