Three Line Break chart using Silverlight

I need to create interactive "Three Line Break chart". It is a type of chart that mainly used in financial/stock analysis.

I downloaded ASP.NET chart cont开发者_如何学Gorol samples from msdn and played around with the "Three line break chart" type that included in the package. It looks great but it is not interactive (chart gennerated is an image ) so I can not just use it.

So, I think I need to use Silverlight, I am wondering anyone knows if there is any free Silverlight chart control package that provides this type of chart out of box?

Thanks a lot.

The Silverlight Toolkit provides some charting controls. Samples can be watch here. An other good library that provides chart ist visifire. But you need a licence if you want to use it commercial.
