jaksmid opened a new issue #8540: Height in Deck.gl Grid wrong if aggregated
URL: https://github.com/apache/incubator-superset/issues/8540
 
 
   I am using Deck.gl Grid to show prices per square meter. As a height parameter, I have `AVG(price_per_square_meter)`. However, I noticed that when there are multiple places at the same location, the aggregate is wrong and even exceeding `max(price_per_square_meter)` when queried in the database. If there is a single place at the location, the height is calculated as expected.
   
   ### Expected results
   
   Heigh is calculated correctly as defined by the aggregate function.
   
   ### Actual results
   
   It seems that the `sum` is used instead of used aggregate.
   
   ### How to reproduce
   Go to the chart with example Grid. Change the height to the `AVG(occupancy)`. Even though the max occupancy in the database is 6, you can observe that the heigh column reaches to values like 36.
   
   ### Environment
   
   (please complete the following information):
   
   - superset version: `0.34.1`
   - python version: `python 3.7.3`
   - node.js version: `v10.15.2`
   - npm version: `5.8.0`
