I have taken several measurement results and am now supposed to plot them graphically, with the error in the y-direction and a root fit. The plot regarding the error in the y-direction was no problem, but unfortunately I don't know how to fit the root. I have only found linear fits and unfortunately I can't find anything on the internet. The fit should look like the screenshot below, does anyone know how to do this in Origin?
