Fig. 3: Characteristic scales of the area-growth field.

From: The multiscale nature of leaf growth fields

Fig. 3

a Spatial correlation between area-growth (AG) values as a function of the distance between them, d. Different line styles and colors represent different time samples (see legend). Measurements were taken as the leaf grew from 6 to 13 mm in length. Dotted lines are linear extrapolations of the data from 0 to 1 mm. b Mean Fourier transform in time over 1200 signals \({AG}(t)\), taken during light-time intervals of 1 day (8 h). ω is the temporal frequency. The signal \({AG}(t)\) is taken in Lagrangian coordinates. The plot does not include the long, dominant, time scale of 24 h (Supplementary Fig. 2).
