Why is it that I have to do the following in root6 and not root5.
Root5
TGraphErrors *gr0 = new TGraphErrors(
tree->GetSelectedRows(), tree->GetV2(),
tree->GetV1(), tree->GetV4(), tree->GetV3());
Root6
TGraphErrors *gr0 = new TGraphErrors(
(Int_t)tree->GetSelectedRows(), (Double_t *)tree->GetV2(),
(Double_t *)tree->GetV1(), (Double_t *)tree->GetV4(),(Double_t *)tree->GetV3());
If I tried running the code as written for Root5 I get an error that states that tree->GetV3() does not return a Double * . I checked GetV3() in root6 source code and it says it is a Double *.
