Graphs on dashboard show statistics of another timeframe than selected

[mztiq]

Describe the bug
Graphs on the dashboard by default should show statistics from "Today" but they show data of a longer period of time even though "Today" is selected.
Only when I select "Last week"/"Last month" and then switch back to "Today" the graph shows data from the correct timeframe.

To Reproduce
Steps to reproduce the behavior:

1. Go to "Dashboard" and check graphs.

Expected behavior
The graphs should only show statistics from today when "Today" is selected.

Environment (please complete the following information):
