Fig 5.

(a) and (b) represent the final configuration and angular distribution of polarization in an elongated tissue with $\mathcal{E}=0.4$. Cell-by-cell magnitudes of the dipoles |P_i| versus the magnitudes of elongations ${\mathcal{E}}_i$, are shown in a scatter plot (c1). The orange line marks the mean magnitude of the cell polarities, $\overline{Q}$. In (c2) the relative angles of the cell dipoles and elongations $|{\varphi }_i^p-{\varphi }_i^e|$, are plotted against the angles of the cell elongations. The average angle of elongation, marked by the vertical red line, is 90° with respect to the x-axis. By definition, the relative angles $|{\varphi }_i^p-{\varphi }_i^e|$ fall below 90° (horizontal dark red line).
