It took me about 5 mn to do this. This is easily extensible…
For now, this is separated from GraphET. Probably it would make sense to move it from Roassal to GraphET.

Hi all,
I would like to plot real-time sensor data that comes from an arduino board.
Is there something to do that in GraphET or any idea to implement it ?
Thank you.
