Bug?: Dashboard -> Widget -> Graph last visits -> Weekly view (no replies)

Hello,

I have the latest Piwik V 2.14.1 running and noticed a wrong output of the graph for the "last visits" widget @dashboard.

When I switch to weekly, I get a wrong graph.

F.e.: Should show from 2015-07-13 till 2015-07-19 and graph shows ~ the past 6 month.

Regards,
Barcelo
