show title on pie chart

[Mehrdad]

Hi,
How can I show legend on chart in RadChart?
I mean insted of showing values on pie ,show the title of that part.
for example if a pie has 3parts with values 10,20 and 30, it draws based on the values but show title of values instead of values itself

Hello Mehrdad,

You can achieve this by creating new ItemMapping and set its DataPointMember to LegendLabel. You will have to specify a FieldName which points from where the data should be taken.
Fore example:

pieSeries.ItemMappings.Add(new ItemMapping("Title", DataPointMember.LegendLabel));

Fore more details checkout the attached sample project.
