Hello ROOTers,

I attache an example of TGraphErrors::Fit. The left plot returns reasonable chi^2/ndf, but the right side doesn't. The result depends on the variable "kScale" in the macro.

The fitting results from the left and the right plots should be the same value mathematically.

Am I doing something incorrect?
