How to draw multi-lines from multiple queries in Kibana

I am new to Kibana and need some help.

I can draw this line chart for a single query (java):

Now I would like to another line for another query (for example python) in the same chart. I am not so sure how to do that. Also "Markdown widget" is the way to add a legend?

Any help would be appreciated.

It is possible by adding the followings:

• X-Axis -> Split Lines -> Sub Aggregation -> Filters

In the filters, you can add multiple ones such as query:java, query:react and so on.
