This is something I have been thinking about quite a lot recently. As a
chart is just an item on a scene, we can add multiple charts to a scene. I
was thinking about adding a chart layout class, that could lay chart items
out in a grid, and modifying the chart class to only appear in that part of
the window.

This would make the mouse interaction easier to deal with, as it would all
just take place in the scene. I am not sure on what the best approach is
with mouse interaction when using the multiple viewport approach. I think
Eric asked about this, and I had been meaning to reply to him but things
have been very hectic in the last few days.
