Hello,
I'm wanting to create historical graphs -- most likely stacked area
graphs -- of some things in a database. Normally I use RRD when I
want to graph things, but RRD files have a fixed number of data
sources when they are created and adding data sources is a bit of a
pain. This will have new values added over time, so I don't think
RRD is suitable. What would others recommend?
I can probably remember how to drive gnuplot if that is the best
answer.
I would prefer to write the bits that get the data out of the
database in Perl, so something with a Perl interface would be great.
The database is only ever a snapshot of current values, so I need to
record the values elsewhere for historical purposes (which RRD is
nice for).
Cheers,
Andy
