In Grafana, how do I use a variable I made and give it as a value into a query search for a graph?

Question

I am trying to take the value of a drop down I created in grafana, utilizing a query variable. I am using SimpleJSON for my database.

I have tried this pattern where: var is my variable that makes up the drop down menu func is my function call for the database query that creates the graph

So then I wrote: f.g.func[$var]

I get a Internal Server Error yet when I call func in kdb+ with the values directly, it works fine. So I think I'm passing in var incorrectly.

Answer 1

For grafana/kdb+ adaptor, the syntax is f.g.func["$var"]-- my above attempt lacks the quotes necessary
