Hi Lucas: You can use the "data defined override" to set the text size based on your classes. Use the fancy "E" under Layer Properties > labels > size. The program expects a number which will become the size.
If the class in your data base is called "class" and it happens to be a number usable as the text size just put "class" in the override. If "class" is a ranking number ( like 1 - 6, with 1 being the largest population and 6 the least) then enter 13 - "class" in the override to get 7 for least and 12 for largest "class". if "class" is a population number then enter a CASE expression like this: CASE WHEN "class" > 1000000 THEN 12 WHEN "class" > 750000 AND "class" < 1000000 THEN 11 WHEN "class" > 500000 AND "class" < 750000 THEN 10 WHEN "class" > 250000 AND "class" < 500000 THEN 9 WHEN "class" > 100000 AND "class" < 250000 THEN 8 ELSE 7 END The overrides can be used to also change font or type style based on data values as well.
