collect your items in normal 2-plot rrds, then combine them using
routers.cgi*Graph.  Here is an example of the number of concurrent voip
calls from multiple devices:
$ grep ALL_CALLS *
1-voip.cfg:routers.cgi*Graph[1-voip.example.net.call]: ALL_CALLS
2-voip.cfg:routers.cgi*Graph[2-voip.example.net.call]: ALL_CALLS
3-voip.cfg:routers.cgi*Graph[3-voip-example.net.call]: ALL_CALLS
4-voip.cfg:routers.cgi*Graph[4-voip.example.net.call]: ALL_CALLS
5-voip.cfg:routers.cgi*Graph[5-voip.example.net.call]: ALL_CALLS

$cat 1-voip.cfg
Target[1-voip.example.net.call]:  CnTWaLKcvCommonDcCallActiveCoderTypeRate&PseudoZero:public:foo at 811-voip-vg-2.austin-energy.net::3:1:1:3
SnmpOptions[1-voip.example.net.call]: authkey=>'0xbf',authprotocol=>'sha',privprotocol=>'aescfb128',username=>'bar',privkey=>'0x4f'
MaxBytes[1-voip.example.net.call]: 24
routers.cgi*Graph[1-voip.example.net.call]: ALL_CALLS
Options[1-voip.example.net.call]:  gauge, noo

$ cat all.cfg
routers.cgi*InMenu[_]:no
routers.cgi*InOut[_]:no 
routers.cgi*InSummary[_]:no 
include: /var/mrtg/cfg/voip/1-voip.cfg
include: /var/mrtg/cfg/voip/2-voip.cfg
include: /var/mrtg/cfg/voip/3-voip.cfg
include: /var/mrtg/cfg/voip/4-voip.cfg
include: /var/mrtg/cfg/voip/5-voip.cfg
routers.cgi*InMenu[ALL_CALLS]: yes

Then, when I select the all.cfg file, I get a graph named ALL_CALLS with
5 lines
