How to plot a running graph from Live XML Stream Data

[JP]

Hi..

I am working on a medical device which will give the various current
reading of various types of parameter from patient body like oxygen
lavel, breathing, tampature etc, and it's a ventilator, so we are
continousally getting live data from this device in the form of XML
Stream. Now i need to plot this live data on a running graph means a
moving graph, i am able to plot this on a .Net (C# Window
application), But now i have to plot this live graph on a web
application (asp.net), means i want to implement some thing like java
applet on .net platform,

So any one can suggest me how it can be implement, becausa data
transfer rate is too high and we need to plot real time data...

Several ways to do this, without knowing the full details it is
difficult to propose a good approach.
How much of data and at what rate does the data arrives? Is it ok to
poll every other second etc.

Few things to consider...

1. You can do this with an AJAX request, need to keep polling
constantly
2. A flash or SilverLight widget that requests data Asynchronously
3. An ActiveX control

Thanks promod,

we are getting data very fast as within 5milisecong we are getting
around 20-80 values for a perticular parameter.
and i am planning to use activeX control for that.
