Hi, When I converted 2D hist in my hbook with h2root, u/overflow was zero filled. The h2root was included in root 2.21/08. *** UTILS_h2root.cxx.orig Mon Mar 29 22:49:47 1999 --- UTILS_h2root.cxx Mon Apr 5 21:08:02 1999 *************** *** 470,477 **** Float_t offsety = 0.5*(ymax-ymin)/ncy; Float_t x,y; ! for (Int_t j=1;j<=ncy;j++) { ! for (Int_t i=1;i<=ncx;i++) { hijxy(id,i,j,x,y); h2->Fill(x+offsetx,y+offsety,hij(id,i,j)); } --- 470,477 ---- Float_t offsety = 0.5*(ymax-ymin)/ncy; Float_t x,y; ! for (Int_t j=0;j<=ncy+1;j++) { ! for (Int_t i=0;i<=ncx+1;i++) { hijxy(id,i,j,x,y); h2->Fill(x+offsetx,y+offsety,hij(id,i,j)); } -- Yasuhiro SHIRASAKI : Experimental Particle Physics, JLC Team Graduate School of Science, TOHOKU University 980-8578 Japan.
