Graphing Cisco Router Interface Traffic Based on Class-Maps

Dear All,

Perhaps, the topic has been covered before; but I did not have any luck 
to find a good  answer to this.

I have a Cisco router with many sub-interfaces and each sub-interfaces 
has policy-maps that permit different levels of traffic of 2 different 
categories: Games and Internet.  A sample configuration is as below.

!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
policy-map BW5M_Internet_20M_Game
  class Game_Class_in
    police cir 20971500
      conform-action transmit
      exceed-action drop
      violate-action drop
  class Game_Class_out
    police cir 20971500
      conform-action transmit
      exceed-action drop
      violate-action drop
  class class-default
    police cir 5754500
      conform-action transmit
      exceed-action drop

class-map match-any Game_Class_in
  match access-group name Customer2Game

class-map match-any Game_Class_out
  match access-group name Game2Customer

ip access-list extended Customer2Game
  permit ip any 172.27.172.0 0.0.0.255

ip access-list extended Game2Customer
  permit ip 172.27.172.0 0.0.0.255 any

int gi0/1.100
  service-policy input  BW5M_Internet_20M_Game
  service-policy output BW5M_Internet_20M_Game

!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

I would like Cacti to produce 2 different graphs for the single 
interface. One graph would show the general(default class) Internet 
bandwidth and the other would show the Game bandwidth.

May I have some pointers to a good documents or Cacti templates for 
that? Or any ideas?

Hope for your kind help.

Thanks & regards,
Khem
