2024-09-07 10:03:23
如下
GET cars/index/_search
{
"size":0,
"aggs": {
"sales": {
"date_histogram": {//按照日期时间聚合分析数据
"field": "sold",//分析的字段
"interval": "month",//按照月份间隔
"format": "yyyy-MM-dd",//日期格式
"min_doc_count": 0,// 没有数据的月份返回0
"extended_bounds":{//强制返回的日期区间，是连续的
"min":"2014-01-01",
"max":"2018-12-31"
}
}
}
}
}
结果如下，拿到数据后方便进行图表分析，这样区间内连续的数据都可以看得很清晰
