display key value

[gorbi13G]

Hello.

How can be printed out value of any key?

For example:

{myhost:system.cpu.load.avg(1h)}

I know only how to print value in the map - in the label of host.
Unfornately it is not printing out value of the time_shift-ed window:

{myhost:system.cpu.load.avg(1h,1d)}

Exists there any method, how to print value of any key??
