At the Program start,i would like to display the Produced Units using a SVG .
The Query return a curent value who is the Produced Units since the Production is running.
So the Produced_Units must be something like this:
Produced_Units = first_value - current_value
where first_value is the Produced Units returning at t = 0
and current_value the Produced Units at t = t + t' ( t' = refresh rate)
So how can i store the first returning value and use it to calculated the Produced Units ? and where? also in the Transaction
oder as a calculated Property ?
Thanks
Request clarification before answering.
Emile,
What is your datasource for this. Is there one? Or, is this still in the conception phase? If you have a tag datasource, you should be able to get production counts directly from a tag source. If not, you might considering storing this information in a SQL table or xml file (depending on some circumstances).
Please provide more information.
