Hi all, very simple question. In the rule-based classification (vector) is it possible to use values of another layer loaded in QGIS?
For example. Point vector and I want to display as red each feature that has a value greater than a value stored in another point layer (or in a table). In the expression builder there are the fields of the active layer. Is it possible to call the fields of other layers? Thanks Cheers Matteo
