```What I was actually trying to do is to limit the peeking of the graphs to
destroy the rest of the data.

the problem in this case still stays a little, since I don't know exactly
what will be peeks... Depending on howmany clients are connected to the
line forinstance.  If i have one client with 100K of bandwith, a peek of
1000K will destroy my graph for example.  but if I have 10 of those
users 1000K is ok and only 100.000K will do some harm (yeah, the numbers
aint that correct :)

I suppose I can change the first 1000 in the line below (CDEF as quoted)
into some function to take the average bandwith + 10% for instance and all
others should be peeked off at avg bandwith + 15% to show they are peeks.

bit late for such stuff, if you know the direct answer and you don't have
to spend to much time, feel free to post.  Otherwise I'll start digging
into the docu's again tomorrow :)

kind regards,
