B-E) Density plot showing the frequency of a value for four, five, seven and eight sided cells respectively, depending of the percentage of hexagons (P6) in the CVT diagrams. The darker region reflects the higher probability of a determine value. Coloured circles represent the average values of each polygon class for the different sets of images analysed in this study. dWL, Drosophila larva wing disc, light green. dMWP, Drosophila mutant wing disc, violet. EYE, Drosophila eye disc, orange. BCA, biceps control adult, dark green. BNA, biceps neurogenic atrophy, dark blue.
