biv_object << Fit Where( WHERE_clause, fit_command );
The Curve message for a Bivariate object enables you to send a message to a curve or line that has already been fit in the Bivariate report. The curves are numbered sequentially in the order they appear in the report.
biv_object << ( Curve[n] << curve_message );
The Set Kernel message for a Nonpar Density curve in a Bivariate object enables you to set the kernel standard deviations for the X and Y values:
biv_object << ( Curve[n] << Set Kernel( x, y ) );
