<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />As the picture show, it is a wafer mapping drawing with Graph Builder .Now i want to show some dies information lke ID &value.
So the problem is that the label is sheltered by the background markers. How can i set these labels top layer . I need your help.

Have you considered using the tooltips?
NamesDefaultToHere(1);
dt = NewTable("Map",
NewColumn("x", Numeric, Continuous, Formula(RandomInteger(1, 20))),
NewColumn("y", Numeric, Continuous, Formula(RandomInteger(1, 20))),
NewColumn("Label 1", Numeric, Continuous, Formula(RandomInteger(1, 5))),
NewColumn("Label 2", Numeric, Continuous, Formula(RandomInteger(1, 5))),
AddRows(100)
);
Column(dt, "Label 1") << Label;
Column(dt, "Label 2") << Label;
// (1) Mouse over some points to see the tooltip.
// (2) Move to the right of the tip to make it persist using the red pin.
// (3) Right click on the tip to see how you can change its properties (colours, tag line etc.).
// (4) Save the Graph Builder script to see how to do this in JSL if you need to
gb = dt << Graph Builder(
Size( 530, 454 ),
Show Control Panel( 0 ),
Variables( X( :x ), Y( :y ) ),
Elements( Points( X, Y, Legend( 5 ) ) ),
);
