Counts from mean accumulator

[nsmith-]

Is there a quick way to turn a Mean() storage histogram into a Double() storage, i.e. retrieve the counts from the mean vector?
It would also be nice to be able to easily plot the variance as well. I guess I'm looking for some general function to do elementwise transform on the storage.

Ok I actually figured it out myself, in case it is of use to others one can do:

hist.Hist(*h.axes, storage="double", data=h.counts())

to extract the counts using the same axis definitions of the original histogram h
