I created an isolated project using this code
http://demos.telerik.com/aspnet-ajax/htmlchart/examples/charttypes/linechart/defaultcs.aspx?show-source=true
when I am using 2015 telerik dlls it works fine
but when I use latest dlls (2017 1st qtr release) Backcolor of plot area changes when cursor is on marker
Plase advise.
Thanks in advance
