This is not a design flaw. It depends on the data element value type
property. The default value type is "number", for which negative values
are perfectly valid. One can set the value type to "Positive number", in
this case the min-max values will never be less than zero.

Title:
  Min/Max generation goes into negative

Status in DHIS:
  Invalid

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.
