Hi Pavan Kumar,
We regret very much for the delayed response and thanks for your interest in Syncfusion products. It is possible to bind more than one Y values to StackingColumn by creating seperate series for each set of Y values. I have attached a sample that illustrates the same in this link below.
http://websamples.syncfusion.com/samples/Chart.Web/6.4.0.15/F74759/Sample1.htmNote: In the sample, values selected from the listbox (in right side panel ) will be bound to Y Axis.
Please let us know if this meets your requirements. Thanks for your patience.
Regards,
Manohari.R
