[ROOT] Getting the RMS of a subrange of a histogram

Hi,

Sorry for what is probably a very trivial question. I am trying to obtain
the RMS of a subrange of a 1D histogram.

Is there any way of doing this without re-drawing the histogram over the
required subrange? I can change the range of the histogram using the GUI,
and the RMS is then automatically recalculated. But I would prefer to do
this in a macro instead. I tried using SetRange() on the command line, but
this didn't work.

Thanks for your help!
