Hi, i have dates that have asymmetric error bars and i’m trying to transform this part of code in a graph that involves asymmetric errors without success. How can i do?
Hi, thank you for the answer but i have already tried with asymmErrors and it gaves me various errors.
Here there is the program. Thank you
costante.c (3.2 KB)
Int_t n = sizeof(freq) / sizeof(freq[0]);
TGraphAsymmErrors *gGf = new TGraphAsymmErrors(n,freq,V,Errfreq,Errfreq2,ErrV,ErrV3);
gGf->SetMarkerSize(0.2); // make very small errors clearly visible
Do i have to use any class? Because root continues to give me errors .
I get no problems but you may miss: #include "TGraphAsymmErrors.h"
It works, thank you
