Real-time time-series plot

Hello World,

First of all thank you very much for such a great library.
I am using this to display static data of ECG and it works perfect for me.
Now I am trying to use this for real-time ECG monitor.

I am having some issue,
The graph need to refresh at interval of 250 ms.
Total points contains in the graph 1250.
When I am trying to add new point in the series and try to refresh the plotmodel, the system slows down.
Kindly guide me to achieve this functionality.


I request you to kindly add example in the example browser for Real-Time Time-Series plot.
Some similar examples are,
