Visual bug in timed graphs

Hi, im getting some visual bugs. I think its changing from winter to summertime. The drop is easy to spot :smile:

This does not happen whem im zooming in:

This isnt a one time thing, happens every year.

This bug was both in 4.1.0 and 4.1.1.

If you think this is a bug then it's best to raise it on

Please include your dashboard JSON as well as sample data and anything else we may need so that we can try to reproduce :slight_smile:
