Data graphic displayed each min even if requested granularity of 10s

Hello,

I’m using Zabbix plugin to retrieve data, in Zabbix admin interface data are correctly collected and displayed each 20s.

In grafana, when I try to increase the granularity from 1min (default) to 10s, data displayed have a granularity of 1 min. (But grafana indicate that the granularity is now 10s)

I don’t know if the problem comes from grafana or Zabbix plugin.

Using query inspector I found that retrieved data from zabbix are correct (see in bottom of this topic )

Can you confirm that ? Have this kind of case ? Can you provide any investigation tips for this ?
Thanks a lot,

It’s ok,
it was a problem of graphic size.
