Even a fresh install of 3.4.5 or 3.4.6 has this issue. Also the new 3.5 beta has it as well.
Seems to be on the frontend as the data is in Zabbix but the graph is not correctly presented.

Hello,

Have you tried to clear the cache or another browser/client machine?

Regards,
Aleksejs!

Yes, the cache was deleted and tried different browsers

In my case I tried different machines and installed Zabbix different times and versions. 3.4.5 onwards exhibit this behavior, 3.4.4 downloads don't.

Have you tried to purge the frontend and perform the clean install? From which version you've upgraded to 3.4.5? Which approach are you using - sources or packages?

Regards,
Aleksejs!

All my installations are from Ubuntu packages.
Clean install of 3.4.6 produces the error.
Clean 3.4.0 graph shows correctly.
Upgrade from 3.4.0 to 3.4.6 produces the error.
Upgrade from 3.4.0 to 3.4.5 produces the error.
Upgrade from 3.4.0 to 3.4.4 graph shows correctly.

The circular graph does not display correctly after upgrading to version 3.4.5. Upgrading to version 3.4.6 does not correct the error. previous version 3.4.4

The same mistake for me. Zabbix 3.4.6 upgrading from 3.4.5 und before 3.4.4 (in 3.4.4 is graph correct)

I Have same problem too after fresh install zabbix server 3.4.6, But on my previous zabbix server (3.4.2) graph is correct.

I've the same bug!

Confirm the same bug. Did not test previous versions of Zabbix as the guys before me, but got the same issue as they do with 3.4.5 and 3.4.6 .

Same bug here with 3.4.6 on Ubuntu.

I am having the same problem to upgrade from version 3.4.4 to 3.4.5 or 3.4.6.

Same issue with 3.4.6 on Ubuntu 16.04 after upgrade from 3.4.4.

Same issue with zabbix server Zabbix 3.4.6 (revision 76823). CentOS 7.With version 3.4.2 was good. And agent Zabbix 3.4.6 (revision 76823).

I have the same setup as andrei and I also have the same issue.

Same Issue here with 3.4.6 Centos 7

Same here. Brand new install Ubutnu.

Same issue I am facing on zabbix server 3.4.6 on CentOS 7.4

RESOLVED in svn://svn.zabbix.com/branches/dev/ZBX-13340

where is the solution in this link: svn://svn.zabbix.com/branches/dev/ZBX-13340

Replaced the changed files of "svn://svn.zabbix.com/branches/dev/ZBX-13340" in my installation and this solved the problem.
You can download the files with a SVN browser like tortoisesvn. Else you have to wait for a release by the dev team.

Thanks a lot Lexley, this temp workaround works well...

Fixed in:

• pre-3.4.8rc1 r78412
• pre-4.0.0alpha5 r78413

svn://svn.zabbix.com/branches/dev/ZBX-13340 is missing.

As the development is finished and merged, this development branch is deleted.

You can access these changes in latest 3.4 branch svn://svn.zabbix.com/branches/3.4 in revision 78412.

thanks Valdis!
