Get Errors for points in TGraphErrors

ROOT
1

Hello all,

I’m looking for a way of reading back the errors for a given point in a TGraphErrors. I know I can get the point position by TGraph::GetPoint(i,x,y), but I could not find a corresponding function that also gives me the errors. Does something like this exist?

Thanks a lot for your help!

Use the methods GetErrorX, GetErrorY or *GetEX, *GetEY, etc
