Figure 5

The gradients of communication volumes depending on social grooming density as distinct from those depending on social grooming frequency. (a) Twitter, (b) 755 group chat, (c) 755 wall communication, (d) Ameba Pigg, (e) Mobile phone, (f) SMS. These figures show compaction of the medians of v for each social grooming density (d/t) for different periods (t is number of days of the data periods). Each line represents entire periods (orange lines), nine-tenths of the periods (green and dotted lines), and eight-tenths of the periods (blue and dashed lines). These are shown when the number of samples is more than 20 (the ranges of d of mobile phone and SMS are short because the sizes of these data sets were small).
