last tagged vs current datapoint

When looking at the progress chart you can see the dots move when selecting the last tagged datatpoint or the history for the past number of days.

The reason is that the default view is on the current datapoint. The current datapoint is not the same as the last tagged datapoint. The last tag is made in the nightly schedule run. And the current datapoint is calculated realtime. So if your project has had updates between now() and the last schedule run they will be reflected in the current datapoint.
