Figure 7a - Principal component analysis of Meristograms. The first (PC1) and second (PC2) principal components describe 56% and 27% of the variance in the data, respectively. Meristograms were generated from hook measurement data in Suppl. materials 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19Suppl. materials 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21.
