PHP 8.1+
We have identified an inconsistency in rendering trend data graphs after upgrading to the version of PHP (8.0 -> 8.1+)
Please see the attached images for reference:
In Zabbix documentation,
For data that show a longer period three lines are drawn - a dark green one shows the average, while a light pink and a light green line shows the maximum and minimum values at that point in time. The space between the highs and the lows is filled with yellow background.

However, after upgrading to PHP 8.1 and above, this documented behavior isn't observed.
