Is your feature request related to a problem? Please describe.
There are some cases where the generated labels for comparison values in a trend chart don't make sense. One such example is creating arbitrary date range comparisons with the native editor. There's no way to display the actual range of values.

Describe the solution you'd like
It would be ideal if we could display the actual ranges in the trend viz or overwrite the labels entirely with custom titles to match the names of the filters.

How important is this feature to you?
being able to pass arbitrary ranges and values to the Trend viz often works but the UX presented to end users is generally not great, preventing adoption of some of these use cases.
