Q: composite stack wafers map but missed to show zero count in location
HiI have one question to stack muti wafers Bin1 count to a single composite wafer map.As you can see, I stack 23 pcs wafers Bin1 to see each XY location Bin1 counts.The question is,there are 3 location (X0,Y8)(X0,Y14)(X1,Y16) Bin1 total count is zero, but this chart can't show it.How can I solve it? Thank you. Regards,Chily
