[rtg] Aggregated graphs - min/max/avg wrong

[Andy Fletcher]

RTG 0.9 from http://code.google.com/p/rtg2/ (but also happens on the
old 8.1, from the sf.net cvs).

When aggregating multiple interfaces the line plots are fine and show
an accurate combined value, but the mix/max/avg figures are incorrect.
Quite often these figures are just of one single DO rather than the
combined total of all DO's.

Does anyone else see this, am I plotting the aggregates wrong, or is there a known fix?

Example plot:

PO=Aggregated%20Physical%20Interfaces%20(data):450:100::1245715707:1245802107&
DO=1:ifInOctets_26:879&
DO=2:ifInOctets_26:888&
DO=3:ifOutOctets_26:879&
DO=4:ifOutOctets_26:888&
LO=1:1,2:aggr,percentile=95,factor=8:Incoming+Traffic&
LO=2:3,4:aggr,percentile=95,factor=8:Outgoing+Traffic&


Kind regards,
Andy
