How to use custom sampling function

[Angshuman]

I haven't come across any code example showing how to use custom sampling for data points in the chart control - at least what to say to the
 radchart.SamplingSettings.SamplingFunction to signify custom sampling or how the sampling delegate would look like ... Please help out.

Hi Angshuman,

Take a look at our help topic Sampling that describes the SamplingFunction. I hope this gets you started properly.

The page you are referring to talks only about built in sampling.

The "GridView's custom aggregating functions. " link takes me to a "Welcome to the Telerik Silverlight Controls Demo Site" which asks me to install Silverlight and all. I can't proceed any further.

Hello Angshuman,

The following WPF demo with full source code demonstrates how to create custom aggregate function for RadGridView using the extensibility API of Telerik LINQ based data engine adding. 
As written in the Sampling help topic I gave you in my previous post you can create custom sampling functions the same way as GridView's aggregate functions.
I hope this information helps.

Kind regards,
