The Fit displays are all located within a Border Box(). If the Border Box() is deleted, the displayed Fits will be deleted..
Report( biv )[Border Box( 2 )] << delete;
Or, you could just "hide" the display by changing it's Visibility
Report( biv )[Border Box( 2 )] << visibility("collapse");
Here is a complete example
Names Default To Here( 1 );
dt = Open( "$SAMPLE_DATA/big class.jmp" );
biv = Bivariate(
Y( :height ),
X( :weight ),
Fit Where( :age == 12, Fit Spline( 1000, {Line Color( {92, 106, 234} )} ) ),
Fit Where( :age == 13, Fit Spline( 1000, {Line Color( {142, 149, 213} )} ) ),
Fit Where( :age == 14, Fit Spline( 1000, {Line Color( {192, 192, 192} )} ) ),
Fit Where( :age == 15, Fit Spline( 1000, {Line Color( {212, 132, 132} )} ) ),
Fit Where( :age == 16, Fit Spline( 1000, {Line Color( {232, 71, 71} )} ) ),
Fit Where( :age == 17, Fit Spline( 1000, {Line Color( {252, 11, 11} )} ) )
);
Report( biv )[Border Box( 2 )] << delete;
// or
// Report( biv )[Border Box( 2 )] << visibility("collapse");
