changing line thickness for a fitted line

Hi,
I do lots of data fitting and I use the follogin procdeure:

a) gr = new TGraphErrors(n,x,y,dx,dy);
gr->Draw("P");

c) TF1 *f1 = new TF1("f1","my fit function",xrange, yrange);
d) first guess of fit parameters
e) gr->Fit("f1", "A");


That all works fine, but then I would like to change the line
thickness and color of the fitted curve, but I can only move it !!
If I move the curve, actually I click on the curve and it seems to
move the data points, then I can change the line thickness/color
of the fitted curve. (I want to do the changes interactively, i.e.
I click on the curve and open 'line attributes').
Is that a bug? How can I get around it?

Thanks
Wolfgang
