I'm trying to create a ClassBreakRenderer and set it on a GraphicsOvelay and cannot get it to work. The renderer works fine on a FeatureLayer, but doesn't work on a GraphicsOverlay that's been created using the same data as the FeatureLayer. I'm not sure what I'm missing here. Is there a sample somewhere that shows how to do this? I pasted the code below, and also attached the repro case, in case someone is up for giving me a hand in getting to the bottom of this. Working with 100.5. Thank you!!! - Mara private async void RenderData() { // Create a new map based on the streets base map.
