How are the symbols drawn in graduated symbology?
When graduated symbology is based on a single field, the symbols are drawn in a sorted order where the larger features draw first and the smaller features draw above them. When the symbology is based on an expression, this sorting does not occur, and some smaller symbols might be obscured by larger ones.

Can a null value be rendered in a sybmology?
1 Answer 1. Yes, it would happen with any data. Quantities is a numeric value and null means no data or no value, thus they won’t be rendered (assuming there truly is no data/null for that feature and it’s supposed to be that way). With Categories you can show null as a value, but not with a numeric based sybmology.
