So doing so, the errors are excludes is there a way to include them?

So you want the errors and the line ? … You ma ro was doing exactly that before…
I thought you wanted only the line…

   t->DrawLatexNDC(0.6, 0.7, Form("p0 = %g #pm %g", f->GetParameter(0), f->GetParError(0)));
   t->DrawLatexNDC(0.6, 0.65, Form("p1 = %g #pm %g", f->GetParameter(1), f->GetParError(1)));

i want just a best fit line and displaying them like Po = 199.234+/-0.0556 and P1 = 1.568e06+/- 0.01545 something along those lines
