Re: Fast copy of axis attributes of a histogram

Thank you Otto.

Perhaps, after TAxis::ImportAttributes(const TAxis *axis) I have to call TH1F::SetBinsLength()? Or TH1 will check automatically that size of the data buffer corresponds to TAxis::GetNbins()? Should I do something else?

Cheers,

Vassili
