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.

    Akin to this, but better:

    Offset should have “Before” …AND… “After” option.

    This should apply to End Time for my use case, which is being able to see a future tag’s future state (using, for example, ‘1 day After End Time’) yes still be able to shift the time range at the bottom.

    Also, preferred that “Duration” be linked to the selectable display time request via the selectable time range tool bar at the bottom of the display.

    See Case Number: 01159287

    Surprised this hasn’t been available for as long as future tags have existed.

    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.
