Trend configuration enhancements to the Event Comparison Display are being evaluated for PI Vision 2021, specifically the ability to show markers and setting value scale options.
As this idea contains many suggestions for Event Comparison Display enhancements, we will update this description on the ability to show markers. There are existing enhancement requests for some of the other items listed. Please add your comments/use cases for the functionality in the appropriate enhancement item to let us know which ones are valuable to you.

Event Comparison: Freehand zoom on event frame overlayEvent Frame Comparison Maximize Trend
If you do not see the specific functionality you need in these enhancement requests, please let us know or create a new idea.
In PI Vision 2020, we added trace options for data markers which show the archive values with the markers. Dropping a cursor at the timestamp of an archived value will show that archived value.
Does this meet the requirements for this feedback request?

This is currently possible by making changes to the Configuration database on the PI AF Server. By creating string-type Attributes at these locations, you can set the timestamp format:
For example, the following format strings will result in timestamps that look like this:
Example time used: 07-Apr-2016 15:45:00
MM/dd/yy hh:mm:ss tt --> 04/07/17 03:45:00 PM
dd-MM-yyyy HH:mm:ss --> 07-04-2017 15:45:00
