nearest neighbors wafer map

Tiff

Hi
Is this possible to filter a specific defect (in defect column) and 8 nearest neighbor and subset the data from main table?

Thanks

Here is an example using the Wafer Stacked data table from the JMP Sample tables that selects the nearest neighbor die

names default to here(1);
dtMain =
// Open Data Table: Wafer Stacked.jmp
// → Data Table( "Wafer Stacked" )
Open( "$SAMPLE_DATA/Wafer Stacked.jmp" );
dtMain << set name("Main");
dtMain:X_Die << modeling type(Ordinal);
dtMain:Y_Die << modeling type(Ordinal);

// For illustration, use only Wafer 1 data
dtMain << select where( :Wafer == 1 & :Lot =="1" );
dtMain << invert row selection;
dtMain << delete rows;

// Create a separate data table that only has the die with defects in them
dtMain << select where( :Defects > 0 );
dtDefects = dtMain << subset( selected rows( 1 ), selected columns( 0 ),
output table( "Defects" ) );

// Remove the defects column from the main table
dtMain << delete columns( :Defects );

// Create a table with the nearest neighbor data from the main table, based upon one of the 
// defect die that has a defect in the defect table.
// For illustration we will pick the die in the Defect table in row
DefectRow = 1;

dtMain << select where( dtMain:X_Die >= dtDefects:X_Die[DefectRow] - 1 & 
dtMain:X_Die <= dtDefects:X_Die[DefectRow] + 1
 &
dtMain:Y_Die >= dtDefects:Y_Die[DefectRow] - 1 & dtMain:Y_Die <= dtDefects:Y_Die[DefectRow] + 1	
);

dtNear = dtMain << subset( selected rows( 1 ), selected columns( 0 ),
output table( "Nearest" ) );

// Display the selected die
dtNear << Graph Builder(
	Size( 512, 448 ),
	Show Control Panel( 0 ),
	Variables( X( :X_Die ), Y( :Y_Die ) ),
	Elements( Points( X, Y, Legend( 5 ) ) )
);
