Plots the Haar spectrum or the Haar periodogram of a series against negative scale -j.

Takes:

sp	The Haar spectrum or the Haar periodogram of a process. Use hper to obtain the periodogram and smper.tilw or smper.spl to smooth it. Use hspec to obtain the spectrum.
skipbeg	The starting 2^(-j)-1 points of the periodogram / spectrum at each scale j are skipped if skipbeg is set to T. Otherwise, they are plotted.
title	Title for the plot.

Returns:

Produces the plot but does not return anything.
