Fig 8

Colored heatmap, visualizing the results of hierarchical cluster analysis. Concentration values are scaled and centered for each metabolite by row, resulting in an improved color representation. Relative workload values (x-axis) are visualized in linear order, resulting in a colored representation of the polynomially fitted concentration curves for each metabolite.
