Find the problem
In package post install script
if [ -e /usr/share/fonts/truetype/ttf-dejavu/DejaVuSans.ttf ]; then
update-alternatives --install /usr/share/zabbix/fonts/graphfont.ttf zabbix-frontend-font /usr/share/fonts/truetype/ttf-dejavu/DejaVuSans.ttf 10
fi

but in Debian stretch
font path is following
/usr/share/fonts/truetype/dejavu

+1
Thanks Renat, that solved my issue. Ubuntu 16.04 has the same path (/usr/share/fonts/truetype/dejavu), not "ttf-dejavu".

You are welcome.

Huge Thanks Renat, that solved my issue as well. (Debian Stretch)

Thank you for the report! It will be fixed in 3.4.3 .

Fixed in 3.4.3-2

I updated to 3.4.3-2 and my graphs are still not displaying correctly. Also same setup. Ubuntu 16.04, MySQL, NGINX. Anyone still have the same issue?

Try restarting web server/clearing the browser cache. Another thing you might want to try is dpkg-reconfigure zabbix-frontend-php.

If the problem is still there, could you show the output of the following command:

$ ls -l /usr/share/zabbix/fonts/graphfont.ttf /etc/alternatives/zabbix-frontend-font

No output.
`
root@zabbix:~# dpkg-reconfigure zabbix-frontend-php
root@zabbix:~#
`

Config below:
`
root@zabbix:~# ls -l /usr/share/zabbix/fonts/graphfont.ttf /etc/alternatives/zabbix-frontend-font
lrwxrwxrwx 1 root root 47 Oct 18 17:25 /etc/alternatives/zabbix-frontend-font -> /usr/share/fonts/truetype/dejavu/DejaVuSans.ttf
lrwxrwxrwx 1 www-data www-data 38 Oct 18 17:25 /usr/share/zabbix/fonts/graphfont.ttf -> /etc/alternatives/zabbix-frontend-font
`

You have everything in place. I guess you just need to restart the web server or something.

Just rebooted the whole Zabbix Server. The graphs still display with no legend.

Zabbix server has nothing to do with that. It's the web server.

But could you show the screenshot of the graph without legend? Could it be that your graph has "Show legend" box unchecked?

oleg.egorov Graph edit form

See my screenshot attached. The settings are enabled. I have check a couple of other ones too.

See the new screenshot.

no legends on 3.4.2

charlviljoen I believe you have something else. On my 3.4.2, this ticket is regarding the text not being displayed, but you can clearly view the "squares" with the appropriate colors.

Why would the Text not display? The settings are all correct. :|

Looks like the font is missing. (c) Captain obvious

Please check the following:

1. Execute php -r "echo realpath('fonts');" in the web root of Zabbix frontend to get the path to font directory.
2. Check if font directory contains DejaVuSans.ttf
3. Check if this file is accessible by web server.
4. As an additional sanity check, you can if file DejaVuSans.ttf is a valid ttf file.

I have excecuted ->

php -r "echo realpath('fonts');"

The fonts is located under

<web-root>/fonts

When I

ls

that

DIR

I get the following. Checked and the files exist.

lrwxrwxrwx  1 www-data www-data   47 Oct 20 10:54 DejaVuSans.ttf -> /usr/share/fonts/truetype/dejavu/DejaVuSans.ttf
lrwxrwxrwx  1 www-data www-data   38 Oct 18 17:25 graphfont.ttf -> /etc/alternatives/zabbix-frontend-font

I fixed it by copying the font file to the fonts root.

Thanks for all your help guys

Thanks, vjaceslavs!

Excuse me n0mad. I have the same issue but I didn't understand your way of doing. May you be more explicit about the way you solve the issue please? where does this script go?

Alou - try to run the following command

update-alternatives --install /usr/share/zabbix/fonts/graphfont.ttf zabbix-frontend-font /usr/share/fonts/truetype/dejavu/DejaVuSans.ttf 10

Its work for me

big thanks n0mad I solved it

Hello!

Zabbix 4.2.2. 
NAME="Ubuntu"
VERSION="16.04.5 LTS (Xenial Xerus)"

The fix

$grep 'FONTPATH' /usr/share/zabbix/include/defines.inc.php
define('ZBX_FONTPATH',                          realpath('assets/fonts')); // where to search for font (GD > 2.0.18)
$ls -alh /usr/share/zabbix/assets/fonts/
empty (no files) - here is the problem
$cp -vf /usr/share/fonts/truetype/dejavu/DejaVuSans.ttf /usr/share/zabbix/assets/fonts/DejaVuSans.ttf
$cp -vf /etc/alternatives/zabbix-frontend-font /usr/share/zabbix/assets/fonts/graphfont.ttf
$service zabbix-server restart && service apache2 restart

Такая же проблема с легендой графиков.

Zabbix 5.0.21

Fedora Server 34

Решил проблему так . Скопировал DejaVuSans.ttf

из /usr/share/fonts/dejavu-sans-fonts/DejaVuSans.ttf
 в папку /usr/share/zabbix/assets/fonts/ 

и переименовал в graphfont.ttf.
