The Biology Experts' pick. Parallel coordinate display of gene expressions per individual. Vertical axes represent expression level for a given gene; horizontal polylines across the display represent each individual. Individuals are stratified in case (pink) versus control (grey). At the top of each vertical axis a histogram displays the distribution of expression levels of that gene over all individuals, stratified by group. The data for genes 1, 3, 5 and 6 are filtered for high and/or low values in this figure.
