Hi Balbir,
Greetings from Syncfusion.
We have prepared a sample based on your requirement with the help of SfChart, SfDataGrid and download the sample from below link.
Note: Editing support is also available in SfDataGrid. So, editing the value in the corresponding grid row will be updated in PieSeries.
Please let us know if need any further assistance on this.
Thanks,
Lavanya A.
