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.

Or

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.
