What I do now is the following
Double_t tphot_bins[51] = { ...some values...};
hz100 = new TProfile2D("hz100","...",19,-5,185,50,tphot_bins);
z100->Draw("abs(rel_error):t_phot:theta >> hz100","prob*flux");
How can I extract the binnumber during the
z100->Draw("abs(rel_error):t_phot:theta >> hz100","prob*flux") ???
Is there something like
z100->Draw("abs(rel_error):t_phot.binnumber:theta >> hz100","prob*flux")
??

ok. I also found SetMaximum/SetMinimum which answers my question
