[Rivet] mapping of DrawNormalized() method in Root

[Debarati Roy]

Dear Experts,
                     Thanks for the feedback. Can you please point to where NormalizeToSum and NormalizeToIntegral are defined ?

Thanks a lot,
Debarati

I agree with David, but Rivet's make-plots system does have some
plotting options for normalisation -- with the caveat that all it knows
about is the values to be rendered.

Adding the plot key NormalizeToIntegral=1 will normalise the output plot
to the inferred histogram area, while NormalizeToSum=1 will scale by the
sum of bin values.

But like David, I think this is much better done at the data histogram
level than in plotting.
