Empty Values
RadChart has been deprecated since Q3 2014 and is no longer recommended for use, as it does not support modern browsers. We strongly recommend using RadHtmlChart, Telerik's modern client-side charting component. To transition from RadChart to RadHtmlChart, refer to the following migration articles:

RadChart automatically approximates missing values between known data points, simply by setting the Empty property true on any chart series item. This works for bar, line and area based chart types. You also have complete control over the visual style of empty values. The empty value style can be articulated separately from the style for the main values.
