Pair correlations of compartment features in top view. At stages I to IV (blue, red, magenta, green) and S (orange), plots show correlations between (A) compartment area ($a_{\text{cz3}}$) and other metrics (B–F) defined in Table 1. Coordinate transforms are chosen in either linear- or log-scale, with natural offsets (e.g., $q_{\mathrm{hex}}$ in panel C, the circularity of a regular hexagon), to produce approximately equally sized contours across life cycle stages. $R^2$ is the linear regression correlation coefficient for stages listed. Similarly as in Fig. 8, geometric distortion-corrected versions of A, B, and C may be found in SI Appendix, Fig. S16. We find that the feature correlations are essentially unchanged, with a slight improvement in cell/compartment area correlation (A).
