Hi Vincent,

Note that most of the functionality in your class is already available via

   TGraph(const char *filename, const char *format="%lg %lg", Option_t *option="");    TNtuple::ReadFile(const char *filename, const char *branchDescriptor="")    TTree::ReadFile(const char *filename, const char *branchDescriptor="")

  see also the TGraphErrors constructors

>From the Tree/TNtuple you can select any of the columns (or expressions
of columns) and in addition have selections on the rows.
