I have a Visio diagram where some boxes are linked to access database queries. These queries count certain values by category, for example:
High: 2
Medium: 3
Low: 1
and so on, however, if any of the categories does not have value anymore, the query does not return it but that does not reflect in Visio. I would like to still see the category in visio but the value would be Zero, is that possible?
