CDEF formula question for Power meter that increases counter

[mathgenius]

I've got a power meter that increases a counter per power usage which is accessable via SNMP.

For every increase of 1000 "ticks" it means 1 kW have been used.

I've added the graph/data source etc. successfully to cacti but it now "only" display the ticks over 5 minutes..

What would be the CDEF formula which I'd apply to the graph to actually get the kW/h on the graph instead of the ticks ?

Thanks

CDEF's use RPN formulas so you need to work out what the mathematical formula you need is, and then convert that over to an RPN expression.
