Graphing Hysteresis

[rbegling]

In Zabbix 2.2 is there a way to create a graph that shows current data with data from the same time X days ago?

I have a trigger expression that compares system cpu load to the load average from 7 days prior :

{Template OS Linux:system.cpu.load[percpu,avg1].avg(1h)}/{Template OS Linux:system.cpu.load[percpu,avg1].avg(1h,7d)}>2&{Template OS Linux:system.cpu.load[percpu,avg1].avg(1h)}>1

I would like to create a graph that has both the current CPU and 7d prior CPU overlaid for a easy visual representation. Is this possible?

Tricky way is to create one more Calculated item with expression like

system.cpu.load[percpu,avg1].avg(1h,7d)

and then use Item for Graph.

When I try that I get:

##Invalid key "system.cpu.load[percpu,avg1].avg(1h,7d)" for item "Processor load (1 min average per core) 7 days ago" on "Template OS Linux": incorrect syntax near ".avg(1h,7d)".

Any other suggestions?

You're right
The construction "system.cpu.load[percpu,avg1].avg(1h,7d)" doesn't work
Only avg("system.cpu.load[percpu,avg1]",1h,7d) works

Sorry
