I would like to have chartSeriesController, so that I don't have to update state whenever new data arrives.

I'm using chartSeriesController, and it works ok. State doesn't get updated for data points (which improves performance drastically), but some other features of the chart stop working. I don't know how to NOT update state for features such as plotBand (vertical line moving with real time data).

It doesn't make sense to use chartSeriesController, if you need to call set state for other chart features that are depended on the real time data.
