C-Sharp (C#) Group: Chart Control something like the equaliser display in MediaPlayer

Does anyone know of a chart control which can display
dynamic values
something like what occurs on the graphic equaliser
visualizations
"Bars and Waves: Bars" on Media Player

see here, for an example of what I am talking about

I especially like how the bar drops off, leaving a peak
indication.

I want the peak indicator to stay, and then scroll the chart
left one
data point, then add a new value on the right.

Any ideas ??
