Max bandwidth is not match at lastest 3 days and at lastest 7 days periods

hi, i used grafana+zabbix to display switch ports bandwidth utility. But, I found that the max bandwidth value is not match. Like this:
lastest 3 days graph.

lastest 7 days graph.

How to fix it ? Get me a answer Please.

it seems to me that they match

Match ?
6/11 00:00 more than 3M at 3 days graph and more than 800K at 7 days graph .
The same day same time and same port, two different value !!!

:no_mouth: I’m sorry, I had understood something else. Maybe you have some grouping period and this period is different ??
