I am using jmp script to draw X-Y scatter plots.

Can I add fitting lines by group using JMP scripts too?

here is sample of the script I copied:

Bivariate(

    Y( :Height ),

    X( :Age ),

    Fit Where( :HDDt == "Schoo_A", Fit Line( {Line Color( {213, 72, 87} )} ) ),

    Fit Where( :HDDt == "School_B", Fit Line( {Line Color( {64, 111, 223} )} ) )

)

If next time, I have 3 groups, School_A, School_B, School_C, do I have to manually add the

3rd fitting line, and choose the colors? I am hoping JMP script can choose color based on # of groups.

Thanks,

Qian

Bivariate() can have an optional Group By() argument.

An example:

Open( "$SAMPLE_DATA/Big Class.jmp" ) <<

Bivariate( Y( :weight ), X( :height ), Group by( :sex ), Fit line() );

In JMP 10 this syntax can be used to remove the first fitted line:

biv << (Curve[1] << Remove Fit);
