Hi there
I have a C macro which give me a Tree is called “tree”, this Tree has many branches “” k1.mean ,time, p, t, k1.error_mean , …etc"".
How can I draw one branch vs other branch but with error bar which take values from third branch.
example: I want to use “k1.error_mean"branch as error bar in k1.mean in this plot :
tree->Draw(“k1.mean:time”,”",“l”).
Of course it can be more clever and build a TGraph, TGraphError or TGraphAsymmErrors according to the number of variables in exp (it is enough to count the “:”).
