Parallel coordinate plots for gene clusters that were added as liver-specific DEGs after TMM normalization. Parallel coordinate plots showing eight hierarchical clusters from the 1578 genes that were added as liver-specific DEGs after TMM normalization. We see that the parallel coordinate lines somewhat follow the expected patterns across the clusters, better than what we saw in the red (Fig. 19) gene subsets, but not as precisely as we saw with the purple (Fig. 17) and orange (Fig. 18) gene subsets. We applied ombre coloring across the clusters in order of cluster size. We used hierarchical clustering to tease apart subtle pattern differences and to mitigate additional overplotting that would occur if we were to plot all genes onto only one parallel coordinate plot. The side-by-side boxplots represent all gene counts in the dataset
