Creating a Multiple Object 95th graph

Hi,

I need to create quite a specific graph and I'm just wondering if it's possible / does anyone know how to do it. I have two separate devices with all of their interfaces being monitored for traffic. I would like to create a graph of total Bps with the sum of bandwidth utilisation from one interface from each device. I also need this graph to show the 95th percentile. Anyone been able to do something like this in the past?

I'm running 'Orion Core 2012.2.2, NPM 10.4.2, IVIM 1.5.0'

Thanks,

Jack
