I'm using QGIS Version 3.16.4. I thought one can do heatmaps by going to the properties of a layer and selecting it under symbolization. But as you can see, it's not available in the dropdown menu. Does anyone know what's the reason for that or how I can activate the heatmap option? The Vector-Layer only consists of polygons which have 3 attributes, so nothing fancy there. Maybe there's a plugin I can use? The two which I found need a timestamp unfortunately, which is not part of my layer
I know you can do something similar by using graduated in the drop down menu, it's explained in this thread but I still want to know why I can't do it with heatmaps.
