X-Axis date ticker for year interval

[dadoonet]

Could you only display years when facets are computed by years?

By now, you are displaying MM/yy when doing

"date_histogram": {
        "field": "dateOfBirth",
        "interval": "1y"
      }

Could you display yyyy instead?

Fixed, histogram ticks change with interval:
if(_int >= 2628000) return "%m/%y" if(_int >= 86400) return "%m/%d/%y" if(_int >= 60) return "%H:%M<br>%m/%d" else return "%H:%M:%S"
