How to generate line graphs (No time series)

Hello everyone, I am trying to generate a graph that shows the evolution of a transaction in different round tests executions.
As you can see, in the X-axis the round test number execution is displayed while in the Y-axis it shows the average response time.

However, I want to put in the same graph another transaction evolution line but im not able to do so. The idea is to have something like this:

line_graph

Im getting data from an InfluxDB datasource.

@rcrinconmiguelangel have you tried adding multiple queries inside the query editor?
