How to do this frequency distribution histogram ,I do not know how to do, want to be able to help me master,thanks!
We don't currently have a native histogram chart for xaml. But you could build your own by bucketing your data, and then using a column chart. Your screenshot has a lot of annotations on it though that may not be very easy to do with the xamWebChart. You can submit a feature request, describing your requirements, and we could look into what might be possible for us to do.
