The above barplots visualise the cross-tabulation of the annotation of the human chromosome 1 by GC content (x-axis) with the annotation by gene density, ATAC, H3K27ac, and H3K27me3 respectively (y-axes). More specifically, we count the number of \(100\,{\text {kb}}\) windows assigned to each state per feature on the y-axes within regions assigned to each GC content state (x-axis), and show them in decreasing shades of grey. Essentially, this is a discretised representation of the correlation between the GC content and the respective other genomic and epigenomic features
