Markers on trend traces is planned for a future release.
Allow trend traces to appear as scatter instead of line. The normal trend symbol seems to perform far faster than XY plot. However, the trend symbol can only appear as a line and this reduces clarity for some use cases.

Once a trend marker has been set, users should have the ability to change the "start time" for other symbols on the display to match that trend marker's timestamp.
Ex. User has set a trend marker at 13:00, and would like an easy method to set all other symbols on the display to show values for that marker's timestamp.
It would be also great to avoid connection line between points as further option in 'format trend' to show plotted points. In genereal I think about discrete data values from measurements, etc.

Customer wants the option to disable the trace (i.e., connection between points) for specific trends to better represent the data.
The data in question is manually entered.
Will this also be an option on the Event Comparison trends? The ability to show only markers and really any format trend options would be nice to have.

The additional capability to show annotations and data quality information by dynamically changing the trace marker and then displaying the annotation data quality by cursor hover would be helpful
add markers, set trend line to "none". Important for general trends. Critical (for our users) in Event Trends. often, samples aren't taken until several hours into a batch. Trendline always ON makes it "connect-the-dots" from previous batch to first sample in new batch. Makes Event Trends unusable for us.
This would be a nice feature to have and also the ability to hide the line and just show the data points would be very beneficial to us.
Include actual data markers (plot each value stored in database) in the trend in PI Coresight(as in PI Processbook) so that we get to know at which point was value stored
