Hello Chandana,
While your image clearly shows the problem, I am afraid we were not able to reproduce it on our end. Can you please confirm, that you are using the latest version of RadChart. If so, please, provide us with a small runnable example, which includes your styles, so that we can reproduce it locally and get back to you with our findings. Thank you.
Best regards,
Ves
