Fit tgrapherrors

WebA TGraphErrorsis a TGraphwith error bars. Several drawing optionsare available for graphs with error bars. TGraphErrorsuses 4 parameters: X, Y (as in TGraph), X-errors, and Y-errors (the size of the errors in the x and y direction). When the errors are not symmetric use TGraphAsymmErrors. The drawing options are the same as those for TGraphErrors WebThe TGraphMultiErrors painting is performed thanks to the TGraphPainter class. All details about the various painting options are given in this class. The picture below gives an example: {. auto c1 = new TCanvas ( "c1", "A Simple Graph with multiple y-errors", 200, 10, 700, 500); c1 ->SetGrid ();

Thus my proposal - in case of a TGraphErrors object the TGraphErrors::Fit should use errors on BOTH axis, X and Y. For me it seems that the TGraphErrors::Fit could be a "direct" copy of TGraph::Fit and the only change should be done for TGraphErrors::GraphFitChisquare, which should be a modified TGraph ...
