   The metric is simply used to overlay a bar chart in the drop down list of each filter column/field.
   So the bar length is defined by the metric result.
   Common use case is often to just use a COUNT(*) metric here, so the user gets a feeling on how much the application of a filter will affect the amount of records taken into account.
   You could as well use a dummy metric of just "1" and end up with a selection that will solely show the distinct values without any further hint to the user.
