Public bug reported:

A very minor bug, but the min/max generation algorithm (which I assume
is some std. dev) sometimes leads the minimum to be a negative number.
Probably not an issue per se for data quality, as the alternative would
be to set it to 0 (unless there is a reason why you would enter negative
numbers), but the chart you get when you double-click a data entry field
is then skewed and does not look very sensible. In extreme cases, with a
few very high values and a few months with very low (as when you have
campaigns or hand-outs), the minimum can be down to minus a lot.
