Hi,
I tried the new version of Kendo DataViz. However, I noticed a degression of how markers are handled for the area chart. In Q3 2013, when hovering a value, the marker would show itself. In 2014, it does not anymore. It's quite bad from a UX point of view because of the loosed context. You can see the problem in your demos too: http://demos.telerik.com/kendo-ui/dataviz/area-charts/index.html
