Well spotted! That’ll be the ‘initial datapoint’, so special for other reasons.

Looking behind the scenes, this is a **binary** goal in terms of [how it aggregates](http://forum.beeminder.com/t/documentation-of-aggregation-methods-would-be-nice/549/4).

That means (to my surprise, I admit) that it checks for the presence or absence of a datapoint. If you enter something (or several things), even if it’s a zero, the day’s total aggregates as ‘ **1** ’.

Those two lighter bold dots are days on which the aggregated value, ‘ **1** ’, differs from the entered value, ‘ **0** ’.
