95th aggregate hrule not appearing properly on ISP billing

[foober251]

I am running a 95th aggregate graph, there are 9 sources of inbound/outbound

I have them seperated into 3 graphs where:
1 shows all inbound
1 shows all outbound
1 shows combined with great of the in+out

When I create the aggregate graph, it uses the standard 95th:6:Current:2 and displays a 0 for 95th measurement
Changing the value to 95th:6:Aggregate:2 displays the proper aggregate of the entire group

However

The ISP billing does not utilize the value, even though php isp_billing.php -list shows the proper aggregate 95th # in mbits, however when creating the graphs and emailing, it shows 0 and the hrule line does also shows 0.

Is there a proper way for the script to properly read an aggregate hrule?
