[mrtg] Re: YMax

[Justin Shore]

Theoretically that should work.  On my modem pool pages I set 
MaxBytes and AbsMax to the same value (redundant but I didn't bother 
to remove that when I copied and pasted it in from another config). 
Them I did an Unscaled[target] dwmy.  Theoretically it should work. 
Try making AbsMax and MaxBytes be the same thing and see if that 
fixes it, just for testing purposes.  If it does then there may be a 
bug there.  You might as well give it dwmy too.  Its the weird things 
that fix the weird problems. :-)

Probably, but that would be too easy. ;-)  Maybe it sets Y to be 
MaxBytes but allows it to display higher values if they exist. 
That's distinctly possible.  Maybe someone on the list knows.  Its a 
logical guess at least.
