Differance of graphic

Central router is Cisco 7606.

I have 2 programmes for analyze traffic: "Cacti" and "NetFlow Analyzer".

And I have very big difference in graphic for interface.
Example Vlan 80:
--------------------------------------------------------------------------------------------------------------------------------------------------
It is from NetFlow Analyzer

--------------------------------------------------------------------------------------------------------------------------------------------------
And from Cacti.

--------------------------------------------------------------------------------------------------------------------------------------------------

From analyzer not all trafic.

Config from router for:

....
ip flow-cache timeout inactive 200
ip flow-cache timeout active 1
ip flow ingress layer2-switched vlan 80
mls ip multicast flow-stat-timer 9
mls flow ip full
no mls acl tcam share-global
mls cef error action freeze
....
