Scatter plot for the log10 ratio of expressions of intergenic ncRNAs and corresponding neighbour genes.

<p>Dots were binned into 80*80 hexagons across the plot area. Different colours represent the dot count in each bin. A represents the expression of 5′ end UTR-related RNAs and neighbour genes. B represents the expression of 5′ end intergenic ncRNAs with UTR-related RNAs removed and neighbour genes. C represents the expression of 3′ end UTR-related RNAs and neighbour genes, and D represent the expression of 3′ end intergenic ncRNAs with UTR-related RNAs removed and corresponding neighbour genes.
