Graph doesn't show all triggers for an item

[acasari]

I have set 4 triggers for free space available item, but the graph from Latest Data, only shows 3 of them (the 4th is when pfree is less than 1%. This trigger works OK since it's firing).

Is there any know reason for not showing all triggers in a graph?

Thanks in advance.

I have the same problem. There are 5 items and 5 triggers, all 5 items will be shown but only 3 triggers. I tried to set graph height but that didn't changed the situation. It would be nice to know if there is a solution for this problem.

Zabbix v2.2.2
Debian Linux 7.5

The limit of max 3 triggers per graph is hardcoded somewhere in zabbix sources. I have not heard if someone has changed that, but it's probably possible to patch the sources.

Thank you filipp.sudanov you have right, it is hardcoded.

I updated zabbix to 2.2.5 an the situation was the same.

Then some search and I found following line in:
/include/classes/graphdraw/CLineGraphDraw.php on Line 442

$max = 3;

and changed to:

$max = 5;

it works

thanks for the pointer, this is still the case with zabbix 3.2.8 but now on line 419.

raise this from 3 to 9 (here on debian)

sed -i 's/$max = 3;/$max = 9;/' /usr/share/zabbix/include/classes/graphdraw/CLineGraphDraw.php

I know this post is ancient, but it solved this exact issue on Zabbix 4.2.

Modifying the $MAX value in /usr/share/zabbix/include/classes/graphdraw/CLineGraphDraw.php
solved the problem for me, on version 4.4.8 it is on line 442 and I raised it from 3 to 10.

Unfortunately you have to re-apply it if you upgrade/update Zabbix.
