Empty Values

RadChart has been replaced by RadHtmlChart, Telerik's client-side charting component. If you are considering RadChart for new development, examine the RadHtmlChart documentation and online demos first to see if it will fit your development needs. If you are already using RadChart in your projects, you can migrate to RadHtmlChart by following these articles: Migrating Series, Migrating Axes, Migrating Date Axes, Migrating Databinding, Features parity. Support for RadChart is discontinued as of Q3 2014, but the control will remain in the assembly so it can still be used. We encourage you to use RadHtmlChart for new development.

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.
