Consultation chart with two queries

[Javier Galán]

Hi all, 

I would like if It's possible to display 2 queries on a chart by sending them through two different dropdowns. That is, one dropdown picks up one query and another dropdown picks up another query but in the chart it shows both results. I've tried to unify the results but it clearly doesn't work because it will behave as if it only selected one select. Any ideas? I also indicate that each dropdown has multiple options so that you can compare a result of one with the other dropdown that also has multiple options.

greetings and thanks in advance
