[rrd-users] Stack valuates together to a daily bar

[Bart Van Der Meerssche]

Hi Mark,

this presentation should be a good starting point: 
http://jokamajo.org/files/homecamp09.pdf

You can follow up on our progress through the jokamajo.org blog. If you 
require additional info, post a comment on the blog since I guess we're 
getting a bit OT for this mailing list.

Cheers,
Bart.
