Change color of fitted line in Nonlinear

BurdenOfProof — Thu, 10 Oct 2024 22:57:07 GMT

I am using the Nonlinear platform to fit y as a nonlinear function of x. In the plot of y=f(x), I want to change the color of the fitted curve from default black to some other color, so I can use copy and paste frame contents to overlay color-coded versions of the curve as I make manual adjustments to the parameters. By right-clicking in the plot area I am able to select Customize and then change the color of the markers, but I don't see any way of changing the color of the fitted curve. Is it possible to do that (change the color of the fitted curve), and if so, how?

Thanks!

One option could be to overlay the graphic script with other graphic script. There might be a way to add pen color to the "Current Model Fit" but I'm not sure how

Names Default To Here(1);
dt = Open("$SAMPLE_DATA/Nonlinear Examples/US Population.jmp");
obj = dt << Nonlinear(Y(:pop), X(:"X-formula"n), Finish());
Eval(EvalExpr(
	Report(obj)[FrameBox(1)] << Add Graphics Script(
		p = Expr(Report(obj)[FrameBox(1)]);
		Pen Color("Red");
		f1 = (p << Find Seg(Top Seg(1))) << get script;
		f2 = Arg(f1);
		If(Head Name(f2) == "Y Function",
			Eval(f2);
		);
	);	
));
