You can use the Go To Time feature to display a specific time on a Trend. For example, you can choose to display the current minute—this causes the x-axis to change so that it only represents one minute (the current minute).
The Go To Time feature can display a variety of times including:
- This Week
- Previous Minute
- Relative Time
- Specific Time.
