Fig. 4: Relative frequency of motifs by classification (after centring).
From: Systematic quantitative analyses reveal the folk-zoological knowledge embedded in folktales

The horizontal label A-Z represents the motifs (see Fig. 3 for details), and the vertical axis represents each category. The colour of each label illustrates the relative frequency of the motifs and the relative frequency within each classification were centred by subtracting the average values of each motif.
