I suspect you are talking about the new ChartView and not the old RadChart control.
I am a little unsure about how you have achieved these features individually, and there is a chance that my proposal will differ from your current implementation. I am attaching a project demonstrating one possible way to get this going.
In it, I have used a SeriesProvider to get the dynamic number of series part working (point 2.). Each series-model has its own timer and updates its data async (point 1.). Note that the update has to be on the main thread.
These two features do not interact with each other (they do not rely on each other, do not contradict and do not complement each other). This is why implementing them together is relatively easy. Let us know if you have any other questions.
