Not a bug per se, but as you note but rather the nature of the min/max
value generation algorithm, which is based on a number of standard
deviations from the mean of the data values.

Work around is to specify the min/max values your self according to your
own custom algorithm.

Title:
  Min/Max generation goes into negative

Status in DHIS:
  Opinion

Bug description:
  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.
