Hi Urvashi,
Greetings from Syncfusion, we have analyzed your query and we are afraid we need more information on this to replicate the scenario at our end. Can you let us know the following information?
1. Can you provide us a screenshot?
2. Can you provide us the code snippet you have used to generate the chart?
This will help us to investigate further and provide you a better solution at the earliest
Thanks,
Michael
