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 WebThese are the top rated real world C++ (Cpp) examples of TGraphErrors::SetFillColorAlpha extracted from open source projects.
