zabbix memory graph

[bchapuisat]

Dear all,

I'm newbie in zabbix and I have difficulties to interpret a zabbix memory graph.
Some jobs failed.
On the first graph the memory problem is clear but on the second graph there isn't just one memory plots.

What the yellow zone represent ?

Thanks for you help.

The second graph is drawed not from plain history data but from trends,

the yellow zone represents min/max values for that trend, green line is average
