With below script, I was able to draw a wafer map with bubble plot in JMP12. The bubble size was set as 35 to represent a die. But in JMP13, the bubble size went to smallest even when same script and same preference setting are used.
Bubble Plot(
X( :X ),
Y( :Y ),
Coloring( :Vmin ),
Bubble Size( 37 ),
Size as Sum( 0 ),
Color as Sum( 1 ),
Label( "All" ),
Set Shape( "Square" ),
Color Theme( "Green Yellow Red" ),
Color Levels( [0.44 0.605 0.77 0.935 1.1] ),
Fit to Window( "Off" ),
Title Position( 0, 0 ));
