Stacked view grouped by terms don't work

[helloworldjs]

Is there a possibility to get the bars stacked after user???

Hey guys,
in the index ‘test’ I have this data:

{"statement": {"type": "cook", "actor": "user1", "timestamp": "2016-11-29T10:14:19.180600+00:00"}},

{"statement": {"type": "cook", "actor": "user1", "timestamp": "2016-11-29T15:03:59.907900+00:00"}},

{"statement": {"type": "sleep", "actor": "user1", "timestamp": "2016-11-29T14:50:29.088900+00:00"}},

{"statement": {"type": "sleep", "actor": "user2", "timestamp": "2016-11-29T15:06:38.894700+00:00"}},

{"statement": {"type": "cook", "actor": "user2", "timestamp": "2016-11-29T15:21:48.873300+00:00"}},

{"statement": {"type": "sleep", "actor": "user2", "timestamp": "2016-11-29T15:23:12.020700+00:00"}}

I get these pictures…:
