I could create the array os histogram as told by Rene:
TH1F *x;
x[i][k] = new TH1F("x[i][k]","title",...)
But now I want to put a protection at the begining of the program, that
means, deleting the
histogram before creating it again. I used to do:
gDirectory->Delete("h");
It work for a normal histogram (h), but it is not working for the array
above, ROOT keeps warning me about recreation of existing histo and
about potential memory leakage. As argument to the Delete command above,
I used a Char_t variable, as:
sprintf(var,"histoname[%d][%d",i,j);
gDirectory->Delete(var);
Could some of you give me some help?
Thanks in advance.
