Relative abundance in histone distributions. Normalized differences in histone distributions (H3, H3K4me3, H3K9ac, and H2A.Z) between broad and peak promoters (from -2 kb to 2 kb) at each position are shown. The y-axis shows the normalized differences in histone distributions between broad and peak promoters. H3K4me3, H3K9ac, and H2A.Z had larger differences than H3.
