I would like to create a personalized filter to help me analyzing what and when was sell in the point of sale during the week, day by day. I'm trying to create a simple filter for each day of the week (on a pre-selected mouth), but I can't figured out what I need to put on domain field.

Model: Point of Sale Orders Statistics

Action: Orders Analysis

Domain:  ??

Context: {'group_by': ['product_id']}

This filter will help to identify what is the best selling of the day and consequently will let me elaborate what I need to promote on some specific days (Mon-Sat) on my restaurant.

Any tips?
