You can use a Where clause to filter by a specific value or column. If you are adding a Where clause to a script that contains column references, you must first resolve the references. For example, the following lines use the Name Expr() function on the Ycol and Xcol references and add a Where clause to limit the analysis to females:

dt = Open( "$SAMPLE_DATA/Big Class.jmp" );

Ycol = Column( "weight" );

Xcol = Column( "height" );

biv2 = dt << Bivariate(

Y( Name Expr( Ycol ) ),

X( Name Expr( Xcol ) ),

Fit Line( ),

Where( :sex == "F" )

);
