This is a follow up question to this question.

I have in QGIS v3.22 two layers: polygon hex layer and points layer.

I want to count all the points that overlap with the polygon layer and display the sum of the points. This dynamic view must be generated in polygon layer Geometry Generator and the desired result must visually correspond to this image enter image description here


1 Answer 1


label expression

  1. Insert this code into Value box in the Layer Styling tab:
  layer:='Random points',
  filter:=intersects($geometry, geometry(@parent))
  1. Replace Random points with your points layer name.
  2. All data must be in one (same) projection.
  3. After you add a new point you have to save the edits and update map window (for example move extent).

Result (gif animation):

  • it counts, but value is "0"

  • yes it is "fid" and I changed layer name correctly ... it shows 0 - I see number in the middle of hex, bud it is wrong number. I double cheked this formula also in help

  • sorry I can't share data, is there any alternative solution? HEX layer is dublicate layer of original layer. I can share only picture.

    it should also work with expression:='1', no need to worry about an existing or populated field

    @RiiPii make sure both layers have the same projection.
