Hi Pallini,
Thanks for choosing Syncfusion Product.
The separator for the digits in axis labels can be achieved by setting LableFormat property as “###,###,###” in chart axis. The separator symbol can be customized based on your local system’s Regional setting. Based on your requirement we have created a simple sample, please download the sample from following location.
