Empty or incomplete graphs longer than 3 days

[aark]

Graphs work until I set interfal to 4 days or longer.
Example:

3 days:

4 days:


Zabbix 6.4 in docker compose.

Checking and unchecking checkbox "Override item trend period" sometimes helps to show graphs, but this behavior is strange.
Also, sometimes trends do not show since some time, while graphs of 3 days or shorter show the full graph

What's your history and trend keeping periods?

[aark]

90 and 365 days

This is probably a bug?

Hello there,

I'm kind of having the same issue on my side, except i'm not running with a docker container and instead am on Zabbix 6.0.7.

Is this issue still occurring to you ? Have you found any clue about it ?
The same 3 day range applies to me, even though values are consistent when checked manually; but not on all items so I'm still dubious about that./
I tried upgrading the php graph draw class to the latest from git but no avail. (Branch : Release 6.0 / Zabbix/ui/include/classes/graphdraw/)

If nothing has changed, should I open an issue on Zabbix Support ? Couldn't find an open one regarding this issue

Having the same issue after upgrading from 5.0LTS to 6.0LTS, the graphs fail to show if I go over a 5-day period. Strange thing too that 30 days has some data showing.
Have tried the steps in here but no change to the DB Zabbix Server 6.2.1 not updating trends - ZABBIX Forums

I am still having the same issue

It kind of got better when I changed the trend and history range on my model's' items instead of my equipment's items
Not the solution I wanted but it does the job
If you somehow find a solution with that please let me know !

I wonder if this is planned to be fixed?
