Here you go. This must bu run as root so either Set UID root (bad!) or
use sudo

for i in $CHAINS
    do sudo $IPTABLES -L -n -v -x| grep ^"Chain $i"| awk {'print $2 " "
$6 " : " $5'}| sed s/packets,/packets/g >> $BBTMP/packets.$$
done

    
Seems to me, its graphs only the packets the default policy of the chain is applied to, i.e those who have not matche any ruly in the chain

True. Personally I use a default "reject" rule hence this will graph what the firewall rejects. Obviously this will not really take into account what is allowed so maybe I was not too clear in my first statement.
