Is it possible to normalize in some fashion the Y axis of trend lines?
Say you have a legacy baseline with some 1000's of checkstyle warnings for instance.
Its not really a useful trend display to see in 'Priority distribution of all warnings' 3000 +/- 5 (the 5 is all but invisible.)
As the count has been ~3000 for the past 50 builds (entire graph), if the range on the Y axis, which is currently say 0 - 4000, was instead, 2900 - 3100 it would be much more useful.
Suggest the min/max counts over the last N builds be used to compute the range.
E.g. range could be 0.8 * min ... 1.2 * max.
This would keep the graph floating in the range of pertubation, and still be able to see trending....
