[mrtg] Graph scaling, limiting peaks in graphs with ping-probe, etc

[Ian Stong]

I'm using mrtg-ping-probe to do some pings across the network.  Works great
and the graphs are informative.  The problem for me is occasionally the
pings skyrocket up to 600 ms.   Once that happens the graph shows the spike
and then the rest of the graph looks almost flat as it is close to the x
axis and scaled accordingly.

So I'm looking for a way to have the graph peak at 200 ms and not graph it
any higher.   I've seen several references in the manuals to various
settings and tried them but to no avail.  Here is a snippet from my config.
I tried Unscaled and setting MaxBytes and AbsMax, etc.... Probably something
simple but just not understanding the correlation with Max/Abs/etc....
