Title:
  Data visualizer line chart shows fictitious data

Status in DHIS 2:
  Confirmed

Bug description:
  I'm running DHIS2 version 2.16 and I have a dataset in which data for
  one indicator have been entered for only a few months.  When I plot a
  bar chart, the data show up correctly (just four months have non-zero
  values).  When I change it to a line chart (no trend line option
  selected), non-zero data appear for all months, even though no data
  exist for the other months (confirmed by the pivot table).

  I've reproduced the same bug in the Sierra Leone demo database (https://apps.dhis2.org/demo/ ):
  Choose Indicators —> Diarrhoea
  Yearly —> Select all years
  Organisation units —> Bo
  The bar chart shows data for just 2013 and 2014 (correct).  The line chart shows the same data for 2013 and 2013, but then fictitious data for 2005-2012.

  I'm nearly certain that this bug hasn't always been present, though I
  can't provide proof; even a few months ago, I think line charts were
  generated correctly.

  I'm using Chrome version 36.0.1985.143 m on Windows 7.
