This question already has an answer here:
I'm trying to use the Group Stats Plugin.
Unfortunately I can not use the plugin: after I enter all the required values, press "calculate" is not active and is always gray.
My problem is that I have a shape of point that are points for animal sightings. This shape is formed by a text field containing the types of areas (beech, poplar, etc.) and another containing the areas value. I need to calculate the number of records that contains a precise type of vegetation and the sum of the relative areas.
Is this possible with Group Stats Plugin?
