Another brain teaser for the scripters out there...
If I have a graph that looks like this:

dt = Open("$Sample_Data/Big Class.jmp");
graph = dt << Graph Builder(
Size( 532, 452 ),
Show Control Panel( 0 ),
Variables( X( :weight ), Y( :height ) ),
Elements( Points( X, Y, Legend( 3 ) ), Smoother( X, Y, Legend( 4 ) ) )
);
How would I make it look like below, after the graph window had been created and using only messages to graph builder itself (i.e. let's consider row states off the table). Via the GUI, I'd do it by right clicking on the marker next to "height" in the legend and changing the marker and color. I can't figure out how to do that via JSL messaging, though.

dt = Open("$Sample_Data/Big Class.jmp");<BR /><BR />graph = Graph Builder(
Size( 532, 452 ),
Show Control Panel( 0 ),
Variables( X( :weight ), Y( :height ) ),
Elements( Points( X, Y, Legend( 3 ) ), Smoother( X, Y, Legend( 4 ) ) ),
SendToReport(
Dispatch(
{},
"400",
ScaleBox,
{Legend Model(
3,
Properties(
0,
{Line Color( 51 ), Marker( "Filled Down Triangle" )},
Item ID( "height", 1 )
)
)}
)
)
);
Thoughts?
