I don't believe there is any way to do this generically.  It is easy enough to create sub charts, but you need to know something about the specific data in the primary chart being clicked in order to present the data in the sub chart.  Here is a crude example of how to "drill down" with dataviz.  Enjoy :)    http://trykendoui.telerik.com/acuL

Given how complicated this would be to build in a generic way, I don't expect they will add the feature.

You can already do it though, simply attach a handler to seriesClick, read the dataItem from the event, then update the chart/data-source as needed to drill in. There's plenty of other handlers you can add too, if you want to allow clicking on the legend or the axis'.

Doing it with a handler you have full control over it all... have a look here for the different events:

And have a look here for ways to modify a chart (e.g. drilling on date, it's not using events on the chart but you could):
