Compare data over different time ranges on the same trend
As a process engineer, I need to be able to overlay traces on the same trend with data from different time ranges so that I can compare different point in time. This may be the same data item over different time ranges or multiple different data items over different time ranges.

The ability to add an offset to the data for a SPECIFIC plotted trace within a Trend of a few plotted traces is crucial to be able to align trends and compare between them.
The end-user should be able to add a positive or negative offset to every trace (HH:MM:SS, or by using PI relative time notations) or drag the trace manually.
Ability to change X-axis of trend lines individually, ie overlap different time periods on the same chart.
Select a trace on a trend and be able to shift the timescale for that trace manually so it is offset from the other traces.
