I've got a table that has a summary table built off of it (with linkage). I wanted to have a graph in the summary table use the table links to pull up a hoverlabel graphlet from the underlying table. I could swear I did this before years ago, but...well if I did it was years ago and I can't seem to remember how to do it, and not having luck finding the answer with my mediocre google skills.
Is this actually possible?
This can be done by explicitly specifying the underlying table as a recipient of << Graph Builder in the expression of the hover label command:

Names Default to Here(1);
new namespace("myNs");
myNS:dt = Open( "$SAMPLE_DATA/Big Class Families.jmp" );
myNS:dt << Summary(
Group( :sex )
);
Graph Builder(
Variables( X( :sex ), Y( :N Rows ) ),
Elements( Bar( X, Y, Legend( 3 ) ) ),
SendToReport(
Dispatch( {}, "Graph Builder", FrameBox,
{Set Graphlet(
Picture(
myNS:dt << Graph Builder(
Size( 656, 556 ),
Show Control Panel( 0 ),
Graph Spacing( 4 ),
Variables( X( :height ), Y( :weight ) ),
Elements(
Points( X, Y, Legend( 3 ) ),
Smoother( X, Y, Legend( 4 ) )
)
)
)
)}
)
)
);
