The bubble series is capable of rendering unsorted data. You will not need to sort the data in code behind. Please, make sure are using the latest assemblies available. I will pass your feedback on the DataTemplate to our developers for further consideration. For now - RadChart allows you to re-template the series as shown in this help topic
, it is dedicated to bars, but the approach is valid for bubbles too.
I have attached a small example -- it shows how to create a RadChart with two bubble series, populated with unsorted data. The series mappings are created in XAML, the entire code-behind is only used to generate data. In addition, one of the series is re-templated to show red squares with variable size (depending on BubbleSize
) and position (depending on XValue
Hope this helps.
