I have a table of attributes with polygons, from the area data I sort from largest to smallest, and when using the command @row_number, he writes the order in which the polygons were created. I want to know how to change the classification of features to the size of the area and then make the count from largest to smallest?
You can use use the Field Calculator to create a new field using the size of the polygons to sort your objects.
This is the expression that you can use:
array_find(array_sort(array_agg("field_name")), "field_name")+1
In your case it will be:
array_find(array_sort(array_agg("ha")), "ha")+1
