Store a vector<vector<TH1F*>>

Dear all,

I would like to store a vector<vector<TH1F*>> inside a root file.
I don’t know what is the better way to proceed ? Does I should use a TObjArray ?
Is there an example somewhere that I can use ?
by advance thank you

Hi Olivier,

Did you resolve this issue?


Ps. A TObjArray is likely to be a fine choice.
