Modifying RAVE visualizations with JavaScript

[miti]

Hello to everybody in this great community!  ;D
The topics discussed here have been helpful on multiple occasions.

The time has come for me to start a discussion, which I think would be of interest to some of you.

I have recently started exploring RAVE and its capabilities.
However, modifying and manipulating RAVE charts seems to be harder than with the regular charts.

I have found this document, which suggests that RAVE charts could be customized in terms of interactivity:
http://rave.mybluemix.net/documentation/Getting_Started_With_Interactivity-events_and_handling.doc

The thing I'm trying to do is something along the line of "Scenario 2" from this document:
2.   Rendering new chart in a popup based on mouse location or selection.

However, I do not know how to approach this or if it is even possible in Report Studio  :-\ (I'm currently working with a standard (non-active) report, but both cases are of interest).

I would be really thankful if someone can guide me on how to approach modifying the RAVE chart in order to show another chart/table as a tooltip on mouse hover.

Thanks so much in advance!  :)
