If you only want to shift the view of the histogram, simply use

xlim([-1 1])
%and/or
ylim([-1 1])

so show only that part of the histogram that appears between (-1,1). (I'm not sure what axis you meant, so try both :) ).

If you instead meant that you want the data to appear between (-1, 1), you'd actually have to adjust y itself to ensure no values are smaller than -1 or larger than 1, but I doubt that's what you're after.

Or if you want to bin only the data between -1 and 1, specify 'BinLimits' when you call the histogram function. See the documentation for that Name-Value Pair Argument on the histogram documentation page for more information on this argument.
