RadChart has been replaced by RadHtmlChart, Telerik's client-side charting component.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.

DefaultLabelValue specifies a format for label values that will be displayed automatically if you do not specifically assign text to a chart series item.

  • Use "#Y" or "#X" to display numbers from the X or Y axis respectively

  • Use "#%" for a percentage of the total sum (of all items).

  • Use "#SUM" to display the total of all items.

  • "#STSUM" displays the sum of a stacked series.

  • "#SERIES" displays the series name.

  • "#ITEM" displays the item name.

  • You can also use the formatting described in this MSDN article Standard Numeric Format Strings. Use curly brackets to contain the standard numeric formats. For example, you can display Y values as currency by setting DefaultLabelValue to "#Y{C}". See examples in the figure below.
