Hi Hucheng, We would prefer to avoid introducing a dependency of the histogram package from classes such as TVector or TMatrix (I agree that it would be more user friendly to do vector.Draw() or matrix.Draw(). one could add functions such as: TH1F::TH1F(const char *name, const char *title, TVector &vector) TH2F::TH2F(const char *name, const char *title, TMatrix &matrix) TH1D::TH1D(const char *name, const char *title, TVectorD &vector) TH2D::TH2D(const char *name, const char *title, TMatrixD &matrix) One could also add something like: TObject *TVector::DrawCopy() TObject *TMatrix::DrawCopy(); TObject *TVectorD::DrawCopy() TObject *TMatrixD::DrawCopy(); The DrawCopy function invoking the histogram package via the interpreter and returning a pointer to the created histogram. Implementing TVector::Draw,Paint, etc could also be considered, but this would imply moving the TVector,TMatrix classes with the TH1 classes.
