How can I tell the atlas-composer to display on one page only all geometries with feature two and all the other geometries should be hidden?
- I have four geometries with two feature-attributes: (1) "Kategorie" and (2) "Merkmal" in the layer with the name "Test".
- The layer-style in the map is made with
categorised
by feature one ("Kategorie"). - The atlas-composer should display on one page only all the geometries which compare the same value in feature two ("Merkmale") and all the other geometries should be hidden.
I think I can write some SQL in the atlas-parameters but I'm not that experienced. When I use e.g., dissolve()
which generates a new layer, then I am not able to hide the other geometries. Any further help is welcome.
map themes
and how they work?map themes
. It seems more and very useful for generating on one page in the composer different map-canvas which are showing different content and style!?
