GetUserInfo() for TChain

Dear ROOTers,

I have a TChain of TTrees each of which has UserInfo object with a TH1F in it. Things are OK when I operate with individual tree. Anyhow, as soon as I ask for :

TH1F* h = (TH1F*)chain->GetUserInfo()->At(0);

I get a NULL pointer. Please let me know what I am doing wrong.

Thanks,
