[mrtg] Strange vertical scale.

[Fred Zwarts (KVI)]

Recently, we upgraded our MRTG to version 2.17.4.
I now see that there are several graphs for which the vertical scales for 
the Weekly, Monthly and Yearly graphs look strange. They do not convert to 
the right postfix (k, M, G, T), but the daily graphs are OK. As an example 
there is a graph which monitors the disk contents of a certain disk. There 
is no change on this disk, so all graphs show the same average, maximum and 
current values (10.9TB and 11.2TB for the two channels, representing the 
actual use and the capacity of the disk, resp.).
For these graphs, the daily graph has a maximum scale of 12.0T, whereas the 
weekly, monthly and yearly graphs show a maximum of 12000000.0M. In the 
previous version all graphs showed a maximum of 12.0T. Although the scale is 
not really incorrect, it looks strange, because the large number now 
overlaps the graph. Is this simply a bug in this version, or is there 
something in the setup that I could change to get back the behavior of the 
previous version?
