[Rivet] rebinning histograms

[Viesturs Veckalns]

Dear Andy,
I have a problem with the script you sent: h is considered as str and no methods of histo1D are applicable.

AttributeError: 'str' object has no attribute 'rebin'

Cheers,
Viesturs

Hi Viesturs,

Yes, histograms have several rebinning methods. You can use a Python
script for simple rebinning like this:

import yoda
hists = yoda.read("myfile.yoda")
for h in hists:
     h.rebin(3) #< factor of 3 rebinning
yoda.write(hists, "newfile.yoda")

Not tested, but it should work: see http://yoda.hepforge.org/pydoc/ and
search for "rebin" to get documentation. You can also pass a list of
explicit new bin edges to rebin() or use explicit rebinBy & rebinTo methods.

Andy
