Peshito from Telerik had a great work around for creating a stepline with Telerik’s new faster RadChartView Control. http://www.telerik.com/community/forums/wpf/charting-kit/stepline-series.aspx I decided to give it a whirl. I realized it would work, but I needed to add labeling and pointmarkers. I was able to get the functionality I needed through a couple of TemplateSelectors. Please look through the sample app for fun.
