some doubts about AGGR()

[LAlvarado]

Hi everyone, there are some problems I'm facing when using the AGGR function  and I have some questions 

for this I need to know if any (of all) of these things can be done

1) use an AGGR to sort one measure in descending order  (on a stacked bar chart with 1 dimmension - 2 measures)

2) how to include 2 dimensions in an AGGR function when I'm only using one in the chart

3) how to obtain the top 80% from a field value

Thank you

You might not need an aggr(). Take a look on the following links:

AGGR...

When should the Aggr() function NOT be used?
