Dear root folks,
I am searching for a way to construct a 2D graph with errorbars from a
file similar to a graph without errors:
TGraph2D(“filename”, “%lg %lg %lg”);
but I found no command therefore. What is the right way to do it or is
there maybe a workaround like getting arrays from a file and putting these
Until now I also tried to split my datafiles for creating three TGraph2D objects: the “real” one and the error ones, but doesn’t look fine.
Thanks in advance.
