real-time charting

Hello,

I am trying to chart data that is streamed via a call to a database or url with the ablity to display that information once I move my mouse over the area. 

I am new to animate and trying to understand how to move from "flash builder" world to the new products.

Any direction to a "how-to" on youtube would be fine. I just have no idea where to start. Google and youtube searching is showing me how to "make a chart" but not how to build a chart while data is coming in real time.

Thanks,

Ray
