Summerize Queries

Hello Guys,

I’m trying to Sum some Queries together and show it in one graph.
I know that InfluxDB can’t Sum Series together but is it possible to Sum for example Query A with Query B and show it in Query C?
I don’t find something like that and hope that someone can help me.
My setup is: InfluxDB v 1.1 and Grafana v 4.6

My use case is:

I have two series from two server with a number of how many users are currently online. This values i want to show separated and together in two different graphs. My idea is to make two queries and hide them, in the third query I want to sum the values from A and B.

I apologize for my bad english
