About the RadChart control, please keep in mind this is our old charting component which has many known issues and limitations. Instead, you can take a look at the RadChartView
suite that has better implementation and improved performance. You can read about the differences between the charting components in the RadChart vs RadChartView
help article. Please check out the new controls and let me know if they will work for you.
