With the rrdtool backend, you can certainly define and add multiple 
sources from different files together.  Using 'AREA' first and 
subsequently 'STACK' to view multiple data sources is particularly 
nice for visualization.

Otherwise, the RRDs and Statistics::Descriptive libraries in Perl can 
probably go a long way towards what you might be wanting for reporting.
