I would like to fit a graph with uncertainty only along x, I do it in the following way: TGraphErrors *gerr = new TGraphErrors(n, x,y,ex,ey); The fit will fail if ey is initialized as an array full of 0, but it will work if I set it as a small number, like 1e-7. Is this the right way to do this fit?
