Figure 2

Rank-based visualization of synthetic data. Synthetic data displayed (a) traditionally and (b) using our rank-based method. This data was generated by creating a single sinusoidal expression profile and for each gene (row) randomly shifting that profile up or down and introducing small amounts of Gaussian random noise throughout. The result is that the genes generally follow the same shape/trend over experiments, but the shapes are shifted up/down from one another. Traditional view (a) masks the similarity between genes, but their relationship is clear in the rank-based view (b).
