I manage a dataset in elastic that stores records of grants allocated across the UK for a charity. There is a need to aggregate the data into regions and then compare that allocation ratios to population statistics. The query to aggregate grants by region is quite simple of course. But I cannot think of a way to then compare this to the target percentages by region.
The regional data is a static dataset that is updated monthly, and comprises of a small table of region names and % of population within the region.
Any suggestions on how I can prepare a bar that shows two bars per region, one the sum of grants awarded and the other the population? Do I need to store the population data on each and every grant record to achieve this?
