At Point of Sale Orders, I wanted to add a Graph View where it can be grouped by (Shop)

I've successfully added the field 'shop_id' to the tree view, then to the group by at search view. through inherited views for each.

I've created a graph view for the object: pos.order

Architecture: <graph string="POS Orders" type="bar"> <field name="shop_id"/> <field name="amount_total" operator="+"/> </graph>

Later I've added a graph view in the action, so the graph view button appears right after the list view (tree)

problem is ...

The graph appears without proper data.

Par type shows 0 sales, though there are posted orders Pie type shows NaN%

regardless of trying to group by other fields.

I noticed that this problem also happens at the account.account model graph view

Could you please help me with this case ?
