I am using QGIS 3.8.
I have a grid (hexagon) and a set of points.
I am trying to select the hexagons containing at least 1 point. So far nothing complicated. Except that sometimes my points overlap 2 hexagons.
So I try to select only the hexagons containing at least 1/2 of the area of the points.
Despite my many attempts, I can't come up with an expression that works.
