Hi Patrick,
It is a pending Adobe Analytics feature- details below:

>>>
Metric polarity
Note: This setting is not currently used in Adobe Analytics, but will be used in the future.
1. Metric polarity allows you to indicate whether Adobe Analytics should consider it good or bad if a given custom event (metric) goes up.
2. It will allow Adobe Analytics to show directional indicators (arrows) for various metrics to add context (for example, week over week comparisons). Example: if "Bugs Submitted" goes up week over week, should Adobe Analytics consider that good, or bad? Other examples: an increase in Email Registrations is probably good. But an increase in Form Submission Errors is probably bad.
In , notice the Polarity column. You can check Up is good or Up is bad.
Best,
Brian
