In Lens there is currently a single metric visualization.
Often to support time series use cases and when analyzing metrics (business metrics or system metrics) users like to use a single metric with another secondary single metric as a quick comparison.

Currently, it is only achievable using TSVB.
It would be good to add either an additional capability in the single metric or a dedicated suggestion that will quickly allow users to select a secondary metric which is either a comparison with a different time (same sum of bytes from last week) or a percentage change from a different time (20% increase or decrease from last week).

@timroes this might also be part of the time series dedicated visualization
