我已经创建了一个如下表

CREATE TABLE consolationstime (TIME_elsp varchar(20),REPONSE_TIME int(11))

值类似于：

1. 2019-11-20 08:11:00，0
2. 2019-11-20 08:11:02，0
3. 2019-11-20 08:11:02，6
4. 2019-11-20 08:11:04，1
5. 2019-11-20 08:11:04，3
6. ................
7. 2019-11-20 20:11:04，6

我尝试使用下面的查询来绘制图形，但是它没有按预期工作。

SELECT
  unix_timestamp(TIME_elsp) as time_sec,max(REPONSE_TIME) as value,'REPONSE_TIME' as metric
 FROM CONSOLATIONSTIME
 where REPONSE_TIME != 0
 and $__timeFilter(TIME_elsp) 
 group by TIME_elsp
