Reactive input to bar chart

[aglenis]

I am trying to create a bar chart from scala.rx values (https://github.com/lihaoyi/scala.rx).
Does anyone have any idea on how to proceed?
I want the bar chart to get updated either automatically when the values change or by pressing a button if there is no other way.
Thanks in advance
