DefaultLabelValue
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:
Explore the RadHtmlChart documentation and online demos to determine how it fits your development needs.
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.
