If you are using RRDTool as your backend, then you can use routers2 as
your frontend and define a stacked userdefined graph with total over the
three targets (see the doc/HOWTO and doc/EXAMPLES documentation with
routers2 for details)

Example here: 
http://www.steveshipway.org/cgi-bin/routers2.pl?uopts=r&rtr=mail.cfg&xgt
ype=d&if=_summary
This shows three variable for email traffic stacked and totalled.
