Fig. 1

Correlogram of 12 male-specific genes expressed as log-counts-per-million from 69 lymphoblastoid cells derived from male (29) and female (40) Yoruba individuals. Variables (genes) are reordered to emphasize the similarity among of their relations. Lower triangle: correlations shown by color and intensity of shading; upper triangle: by circle filled proportionally to the correlation strength. Given the symmetrical nature of a correlogram, often different representations are used for the lower and the upper triangles. Source for the data [27]
