We currently use ObjectPlanets EasyCharts and they allow you to define a drill-down URL that can be associated with each line or bar. This allows us to have a bar chart on a page with a data grid. When the user clicks a bar, a URL is posted to the server that populates the data grid with more detail on the selected chart item.

It would be nice if the charts supported more marker types.  Currently only circles, triangles and squares are supported.  This poses a problem when you have more than 3 series and want to show distinct markers for each series.  I suggest adding support for a cross and star.  It would also be nice to support custom marker images.

Your silverlight Timebar is Briliant.

I suggest you implement something like that(maybe a litle less complex) in KendoUI.
