Thank you for the question.
I have attached a runnable sample application that demonstrates how to implement a legend for RadPieChart.
For the legend I use an ItemsControl and set its ItemsSource to the DataPoints collection of the chart Series. Each data point has a DataItem property that is the underlying item from the view model. Via a value converter using the ChartPalette.GetEntry(series
, point index
) method you can get the corresponding palette color for each data point. You will also need to reset the ItemsSource of the legend each time you add/remove point in order to update the legend.
I hope this should give you a basic idea of how you can implement a legend. Please, do not hesitate to contact us if you have further questions.
