Distribution of B/T attribute versus the EFIGI morphological type for the 4458 galaxies in the EFIGI catalogue (see Table 2 for the correspondence with types). In order to see the relative density of data points, they are spread in the horizontal and vertical direction, hence the apparent rectangles. The weighted mean and weighted rms  dispersion in B/T are also plotted for each type along with the corresponding number of galaxies. This graph shows the strong correlation of morphological type with B/T.
