Trend: Time Range: Duration and Offset - Add option to support start time
Currently the Trend object's Time Range has a Duration and Offset option which will take the End Time of the display and a specified duration for the trend's timerange. We need to have the ability to do the same based on the Start Time and a duration. Can you please add a new Time Range option "Duration and Offset from Start"?
The use case for this is that we are comparing batch phases against a golden batch's phase, but the phase duration can and do differ. Having an option to have the trend start at a selected batch phase's start time with a duration that we specify will allow for a clean comparison between the 2 trends.
Agree on having a start time offset.
For batch comparison we use the event comparison function. Each phase has it own event. Downside this is not a control room friendly like a main display. We would need something like the event comparison on a main display using the golden batch as the constant.
