If you set Maxbytes to 1Mb, (and Abmax the same), values above that will 
be ignored. How will it be plotted? Without unknownaszero, I thought it 
simply re-used the last known value, and would flat line. Since your 
backup may ramp-up to the high level, the flatline would be quite high. I 
think once you move on to RRD you get it handled differently.


Plot the same value twice, once showing real traffic, with big peaks but 
unreadable daytime, and once with a cut off top. Then you can look at 
eiter graph to give you what you want to see.
