The statistical Text displays are editable through the Customize... dialog.(Right click on the graph and select Customize). You can change the font, color, size, but it does not allow for the position to be specified. However, below is a very klugie way of getting what you want
Names Default To Here( 1 );
dt = Open( "$SAMPLE_DATA/Big Class.jmp" );
gb = Graph Builder(
Show Control Panel( 0 ),
Variables( X( :height ), Y( :weight ) ),
Elements(
Points( X, Y, Legend( 1 ), Jitter( 1 ) ),
Line Of Fit(
X,
Y,
Legend( 4 ),
Confidence of Fit( 1 ),
Confidence of Prediction( 1 ),
Degree( "Cubic" ),
R²( 1 )
)
)
);
fontobj = seg = Report( gb )[Framebox( 1 )] << Find Seg( "TextSeg" );
zip = seg << Get Text;
seg << Set Text(repeat(" ", 150) || zip
);
