Hi all, I've imported data from mysql into elasticsearch that has a date field with unixtime format(such as: 1514851200). I want to group by date with this field.  
i had using query:  
"histogram": {  
"field": "sentdate",  
"interval": 86400,  
}  
But it not correct, Please help me. Thanks a lot!
